Earl, once heater box and hoses are in place, does cardboard glove box insert get installed from below dash or folded up and pushed thru the open door?

Can the 65 mustang heater box be installed with the glove box in-place or must cardboard glove box be removed and reinstalled after heater box is installed?

Fred did my 3939S and it's Beautiful. Fred does best job.

And it has the correct red star above the F, M and C on the canister. Nice piece.

Would seem engine with somewhat lower vacuum and a "large" PV would have bit too much fuel due to PV spring keeping valve in open position. 
Sorry about the PV discussion but it relates to jet sizing.

Ok. At idle, engine has highest vacuum reading and power valve is kept closed by the spring and vacuum. When throttle plates are opened under acceleration, vacuum decreases and spring tension is decreased allowing fuel to get sucked thru the "small" end of PV and exit into the two holes in the metering plate that eventually go to the main jets effectually increasing jet size by like 4 numbers?
Am I getting there?

So PV has no effect at idle, unless PV is ruptured or PV is way too small for the engine vacuum and opening way before it should. If engine pulls 13 inches of 'vacuum", PV should be a 6.5. However, if engine pulls 13" and a 3 or 4 PV is installed, lot of fuel will be pouring into engine at idle?

The 715 metering block has a small ridge I assume is designed to help the gasket to seal the parameter. If a metering block is warped, can it be "fixed" by milling it a couple thousandths until it is "flat"? Understand this will eat the ridge off, but modern billet plates are milled and do not have the ridge.
Thanks

68 disconnected/bad tach, engine will not run...

bump. Still looking.

If engine is running and not chugging after key is turned off, almost has to be solenoid. Not expensive and easy to replace.

Ford produced three different steering boxes for the 65 model year.
1. HCC AW, Power steering, 16:1, 3 3/4 turn lock to lock.
2. HCC AX, Manual steering, 16:1, 3 3/4 turn lock to lock.
3. HCC AT, Manual Steering, 19:1, 4 5/8 turn lock to lock.

The 65 GT350 was shipped with the HCC AX box with the unique pitman and idler arm to quicken the steering even more.
Is there a difference in the HCC AW and the HCC AX 16:1 boxes? If so, what is it?

Second question. What determines the ratio? Is it the worm gear at end of main shaft or the block gear with the ball bearings or the gear at the top of the pitman? Or all three. Is there a difference in the cases for manual versus power?

Thanks

Sent you a PM

When owner turns key from "on" to "Start", does it snap back to "on" or do you almost have to physically move key back to "on"? Could be key mechanism sticking. Hear these cars have had challenges in this area, after 50 plus years.... But then so do I...
