Other then doing some google searches and watching online content I don't have somebody walking me through this process. The reason the name fits is because HELP is needed to get this done. If you live in the Midwest and want to physically help OK. If you have knowledge to share I will gladly use that help.

The tear down has begun. 6 body bolts out I think separating the body and frame is where to start?

THANKS!

My goals for H.E.L.P. 1st phase:
1. Driver quality build.
2. Fix cancer
3. LS powered with a power adder. HELP decide which way to go.
4. Pro-touring style
5. Modern suspension with air adjustability. Is Ride tech the only performance engineered option?
6. Original 4 speed car so either a 5-6 speed option is desired because I would like to make some longer drives when completed. Which transmission route to go?
7. Keep an old school feel to the interior but incorporate in some modern comforts to seats and electronics.
8. Not get caught in bodywork prison.
9. Focus on function and reliability before 2nd phase
10. Useable before my 12 and 14 year old's are done with high school
11. Learn some things, have fun! ]]> AMSOILGUY https://forums.maxperformanceinc.com/forums/showthread.php?t=886310 Core support https://forums.maxperformanceinc.com/forums/showthread.php?t=886288&goto=newpost Thu, 16 Jul 2026 00:44:03 GMT Wrecked my 64 goat, I need a core support, anybody have one for sale.

1964 GTO on BaT with some discrepancies?


The Manifest seems good but does not match cowl tag on car.
Vin on car matches manifest. (but not cowltag)
Vin looks like it could have been replaced, but I'm not sure what they looked like originally.
VIN and manifest are Pontiac plant, cowlatg is Fremont!
Plus the engine in car is not a 64 engine. (maybe 65/66?)

Little project I'm been completely stuck on. I bought LED 1157 bulbs for my tail light/brake light. Problem is my tail light socket is so old and weak the metal contacts don't even contact the LED bulb base. Easy fix normally, just replace the tail light sockets with new ones and good to go.

My problem is that the sockets that everyone says go to a 65 don't fit at all, they're entirely different sockets and not compatible. I tried the Wells version as well as the AC Delco version, neither of which work. I have included a photo of my sockets, vs what the internet is saying is correct. As you will see, they are entirely different parts. What makes this so frustrating is that I cannot even find proof of my socket's existence, other than my own. I cannot find a picture of the correct socket I need, nor can I find any information about GM possibly switching part numbers through production. It's as if the sockets I have never existed. But I need 2 of them. How do I purchase parts that don't exist? I do not want to buy used.

Thanks for helping!

I don't have the VIN #.

Hello everyone, I am trying to track down the 1964 Pontiac GTO hardtop coupe that I originally ordered new.Here are the exact factory specs:Body: Hardtop Coupe (Twin fake hood scoops)Exterior: Aquamarine Metallic with a White topInterior: White/Parchment interior with the optional simulated wood Custom Sport steering wheelDrivetrain: 389ci V8 (4-barrel carb), Jetaway automatic transmissionHistory: Early production phase. I traded it in at Big R Volkswagen, Inc. in Big Rapids, Michigan in 1968.I do not have the VIN. If anyone owns an Aquamarine '64 matching this description, or has seen one in registries matching a Michigan delivery history, please let me know!

I know this is a long shot, but have run into deadends elsewhere. Other ideas appreciated.

I have a few misc parts that I stripped out of a 1964 Catalina and before I get rid of them I wanted to make sure they are not the same as my 1965 LeMans.

The parts I am referring to are the heater assembly, accelerator pedal parts, park brake pieces, defrost duct at dash, fresh air cables.
The only part numbers I have at the moment are for one of the plastic heater box outlets, p/n 543892, and two vacuum diaphragms, p/n 3143146 and 3144212.

Unfortunately, I can't just compare most of this stuff to my LeMans because it has had a hard life of people using whatever parts happened to be around just to keep things functioning.

Thanks in advance. ]]> justincampbell https://forums.maxperformanceinc.com/forums/showthread.php?t=885959
