I am looking for an original thermostat housing and vacuum advance for my 1968 GT350. Please let me know what you have.
Thank you,
Corey
Which one do you want? A 4 speed uses the same one as a CJ.
Do you want a correct date coded one?
GT350- CJ?
Follow my advice- ignore Doug. He is not well
A 302 thermostat housing is different from a 428 housing

302 has water pump hose connection (ignore arrow)
Top mount vacuum tree
That engine has no distributor. My engine has one. I want a picture of an engine with a distributor!
I'll take a picture of the vacuum advance mechanisms I have later. To me they look the same as the CJ unit.
Agreed on the thermostat housing and tree.
You are correct the vacuum advance is the same

Only on the 4 spd though. The 302 automatic vacuum can is entirely different.
I have two of the 4 speed housings. I think I can cosmetically save them by vapor blasting and then clear coating the steel housing?
I don't know how else to keep it from oxidizing.
I was actually surprised to find that the vacuum advance calibration of the two engines is the same. I didn't expect that.
Incidentally, my vacuum tree has traces of blue overspray on the hex.
4spds are dusl vacuum advance, autos are single pull, the exception is the GT500, those are all single vacuums
I do not require a correct date code but it is always a plus. My car is Feb 12. But again not a hard requirement.
We have one vacuum advance here. CORRECT $225 . Looks NOS.

Just to be crystal clear are looking for a thermostat housing and a distributor vacuum advance or thermostat housing and the vacuum switch that goes in the thermostat housing?
Yes!

It looks good Phil
Just think how many prople you have helped
Yes Bob as Pete said I am looking for all 3 pieces. Vacuum advance, Thermostat housing and the vacuum tree on the thermostat housing.

Please be aware that the CORRECT vacuum advance for the J code 4 speed is not the same as CJ . The J code is marked A12 while CJ ( 68-69 428 speed )is marked HP6. They LOOK similar,but are not the same. 1968 version of the A12 uses the brass threaded fitting on the advance side.
Thank you Dizzy.
I got a nice used a12 with the 68 threaded nipple and nos in autolite box if needed. Also have thermostat housing with vacuum trees on them and some c8ae trees off what is id # on the thermostat housing c8oe or?
Special Ed,
I have no idea whether the T housing should be C8AE or C8OE or... Maybe someone else (Pete) will chime in. But I am definitely interested in both the A12 advance and the T housing with Vacuum tree. Can you PM me with your prices and pictures? I also PMed you with my email and phone info if you want to send directly.

I just looked thru my box of t-stat housings and I got 2 nice c80e 68 302 late 67 date cast with late 67 dated vaccum trees still in place proper factory positions of which is best way to buy one since they are very hard to remove and brass nut fitting gets corners rounded off when u try and remove them and the 3 cast on nipples break off easy. 68 302 t -stat housing is c8oe and has smaller bypass hose nipple cast in it then in 69 and up 351w its c9oe with bigger bypass hose nipple otherwise they look the same and this is why 68 bypass hose is c2oz and 69 is c9oz different size bigger hose. Replacements are cast iron housings that are incorrect.
