What is the differance betteen the 64 Lemans Rad core support and the 64 GTO's? Is it where the support bushing goes Round bushing or square. Or is the suppost altogether different.

In '64 all the tri-power GTO's got the tall radiator, even if it didn't come with air conditioning. As Todd said, the core supports are the same except for the extra two inch depth on A/C or tri-power.

Well, the absolute correct answer is that ALL 1964 GTOs used the A/C (or 2 inches deeper) radiator support. It did not matter if the GTO was a 4 B.C or 3/2 B.C. car, they all got the deeper radiator support. These were originally installed on all 1964 GTOs, and all 1964 Tempest & LeMans 326 cars that also had A.C.

Marv, I beg to differ. I just picked up a '64 GTO parts car that has the shallower(not 2" deeper)core support.

[Pontiac Marv]

FritzCat,
I am assuming you know the history of this parts car you picked up recently since the day it was delivered to the original owner from the statement you made. If the answer is no, answer the following: 1) Do you know if is a real GTO? 2) Could the radiator support ever have been changed by a previous owner? If you are not sure about the answers to these questions, and if this is the only 1964 GTO you have seen with the Tempest/LeMans radiator support (my assumption as you did not mention any others), how can you make this statement?
I make my statement based on several Pontiac parts books I have from 1964-up, Pontiac parts histories from 1964-up, and the dozens if not hundreds of 1964s I have seen in the past 15 years.
Will anyone else back me up?

[FritzCat]

Marv, I'm sorry. It's definitely a real GTO, but the core support certainly could have been changed. The guy I got it from is sort of a space cadet and doesn't remember a lot, since the car had been sitting since he wrecked it 18 years ago. I should know better than to comment on a part I haven't seen a lot of. I'll keep checking any '64 GTO core supports I run across.

Let me get this straight!!!!! ALL GTOs had the taller core support for the larger radiator, because of the high performance....... SOME of the Lemans and Tempests had the taller core support depending on the engine size and/or if it had air....... One other question, does this hold true for the 65 cars?

This I know for sure. The 65 GTO, Lemans & Tempest all used the same supports, unless it had A/C or HD cooling. The thing that through me off was when I just ordered new bushing for my 64. I had to use the round ones, but Performance years also listed square ones so I though it might have had a Lemans support in it. It is a second owner car with no damage on it.So I am guessing Pontiac changed the run or maybe if it was made at a different plant it must have gotton the square bushings/support put in.

Sorry Rocco, you are the fourth person to not be completely correct. I hope to answer all of the previous postings above by listing all 1964-65 Tempest, LeMans, and GTO radiator supports that were made, plus their applications.

1964:
Part #9774305 (For 15 1/2 Inch Tall Radiators) - All Tempest & LeMans 6-Cylinder Cars; All Tempest & LeMans 8-Cylinder Cars Except A.C.

Part#9775061 (For 17 1/2 Inch Tall Radiators) - All Tempest & LeMans 8-Cylinder Cars With A.C.; All GTOs

1965:
Part #9779848 (For 15 1/2 Inch Tall Radiators) - All Tempest & LeMans 6-Cylinder Cars; All Tempest & LeMans 8-Cylinder Cars Except A.C.; All GTOs Except A.C.

Part #9779849 (For 17 1/2 Inch Tall Radiators) - All Tempest & LeMans 8-Cylinder Cars With A.C.; All GTOs With A.C.

To Answer Rocco regarding the radiator support bushings, the square ones are correct for the 1964s, and the round ones are correct for the 1965s.

I hope this response will conclude this topic!

[Zimtok]

I think that sets everything straight......But it has been a fun ride.

Marv and others, sorry I was not available for a while. Marvin is correct, all 64 GTO's used the deep support, as well as 64 Tempest/Lemans with A/c. All non a/c T/L used the shallow one. The square radiator support bushings were used in 64 and not 65. I believe they were replaced mid 64 by the round ones, as I have seen several late original 64's with the round bushings.
