The administration of the generic and inexpensive anti-malarial hydroxychloroquine is starting to show good results in the treatment of COVID-19.

Some folks were already here and setting up for the Boise Roadster Show slated to open tomorrow. It was cancelled this afternoon.

I wonder if the vendor closings are partly because fewer folks are putting many miles their car.

When I bought my car in '83, these old Mustangs were a common sight - just another cool, old "used" car. Daily usage wears parts out or subjects them to damage that warrants replacement.

These days, I see very few '65/'66 Mustangs on the street, so maybe there's less need for replacement parts.

Actually, I think this is the one at Robins AFB. The museum is just a mile or two south of the base.

I've never been there, but I'd sure like to visit some day.

OK, good to know!

200212: Brian, you were correct after all. The Hickory Aviation Museum is close to Robins AFB only if you think a 325 mile drive is "close".

I had used the original (not the subsequently corrected) website link to find the location.

+1 An absolutely gorgeous aircraft! I have loved these since I was a kid.

I had the opportunity to buy one of these 20+ years ago. After my broker investigated, it needed quite a bit of work. Also, after being further edjumacated, I didn't think I was prepared for the routine maintenance it would require. I bought a Cessna T210M instead. Not nearly the same ramp presence.

Owning a Beech 17 has to be a true labor of love.

LOL!

I don't know about Chinese versions. I was just concerned because I didn't buy this DL myself back in the '90s. I let my drive-line guy source it. After seeing the beautiful machine work on 1109RWHP's lightened Locker and my Moser Wavetrac and then comparing that to the rough casting on my DL, I was thinking I might have let my guy pull one over on me by buying a sub-par unit (assuming one exists). It's good to learn that this rough finish is not unusual or indicative of a poor-quality DL.

Here's a couple photos of my Moser Wavetrac. I'm often impressed with the machine work of many of these internal parts. They are works of art. It seems a shame to cover them up!

Thx to you and Doug for your input!

I'd appreciate some help identifying my 31-spline Locker in preparation for selling it. Would this be an early-design standard unit? A later "Soft-Spring" unit? An Chinese Eaton knock-off?
I tried to educate myself using the internet. I found a number of good websites covering the Ford 9" and a bit about differentials and Lockers, but none that dig into this level of detail.

The cast-in number says "02833  M - 3". (Goofy looking "M")

There is what appears to be a date cast-in as well, but it is mostly machined away on the ring gear surface. The visible part shows the date as 4/1/82 or '83 (or maybe '92/'93?).
This unit was made on April Fools Day?!

There are two stamped numbers on the machined surfaces: "64530" and "64531".

The housing is machined, but when it was turned, only about 50-60% of the cast surface was removed. Does this indicate a level (or lack) of quality? Does this affect its resale value?

This DL was installed in '93 and removed in '16 before being used. Diff gear oil was never installed. Only the one axle bearing was still attached when I got the unit back from the axle shop.


Is this info useful to you Locker Gurus to help figure out what I've got?

I apologize if this is going too far afield of the original topic. Please feel free to move it to the appropriate section.

With all this DL love, looks like I should dig my Locker out of storage and put it in the sale section.
It's 25 years old and never been kissed!

Many of us do put our old relics on the track. But, why settle exclusively for old vs. new?

I've had my '65 Fastback since '83 and all along have also had a more modern performance car. Last summer, I sold my C5 Corvette and acquired the '19 GT350. I still look forward to finishing the '65 and getting it back into Autocross and a few vintage-type track days, but I've discovered that the Shelby is a blast on the tracks. It's obviously a very different experience than the '65 at speed, but I like them both in different ways.

I would have looked harder at the GT500 or the C8, but I just like rowing my own gears.

Take a look at torque sensing Limited-Slip Differentials (or LSD), also known as torsional differentials. These units sense the torque on the wheel with the least traction and they mechanically multiply that torque to the other wheel. The most popular version seems to be the Eaton TrueTrac Differentials. They get good reviews as being reliable and reasonably priced.

Back in the 80's, I ran a Traction-Lok differential for Autocross, but had to change the clutch-packs occasionally. On my current rebuild, I originally installed a Detroit Locker in my Ford 9", but my project has taken so long to complete that the new torque sensing differentials came out in the mean time. I was told that when using the Locker in a performance situation, the sudden engagement and disengagement can upset the car. In addition, there is a disconcerting "clunk" when the Locker disengages. The torque sensing differentials seem to be widely recommended as superior in most situations.

I chose the Moser Engineering Wavetrac torque-sensing LSD even though it is more expensive because it has a lifetime warranty (regardless of your horsepower!) and it works under no-load conditions when one wheel has zero traction. Since a torque sensing differential multiplies the torque on the lower-traction driven wheel, when that wheel has zero-load, the typical torque-sensing differential provides no torque to the other wheel (because any number multiplied by zero is still zero). This would occur only in rare situations like very slick ice under one drive wheel, or when one wheel is completely off the ground as in rock crawling or track-curb jumping. Under no-load conditions, a typical torque-sensing LSD acts like an open differential, whereas the Wavetrac acts like a spool (both wheels rotate at the same speed). Wavetrac's are popular among the off-road crowd where the Locker is also still widely used.

I hear Idaho is not as nice as it used to be either....(climate change has hit there also).

That's right - Idaho sucks.

Keep moving along. Nothing to see here.

Electrical cord in the right-front engine bay, hub? Electric fan controller?
By the way, did you enlarge the radiator opening to get the dual-fan system installed?

I'm hoping to get restarted on my project over this holiday break, so I might have some progress to post next month. Had some 'circle of life' drama to deal with recently. I also got a 2019 GT350 and started doing some track days. That's been a huge, but fun distraction!

I'm really enjoying this thread, Ruben!

I see some of the same equipment that I'm installing in my Restomod, for instance the TCP steering & front suspension, dash, trans, etc. but your build much more ambitious than mine.

Keep it coming!

I agree with that!
While using the 3M caulk, I quickly learned to use tight-fitting disposable gloves.
