radiator support bushings for 67 or 68

[legends]

Does anyone have a picture of a radiator support bushing for a 67 or 68. I am trying to put a 67 support on a 71 frame and want to make sure i purchased the correct bushings.

The support cushions/mounts are the same for 67-72, These are on GMC Pauls site.



In case you didn't know, you cannot use the 67/68 radiator core support with 69-72 fenders/hood.

They 67-68's are thinner than 69-72 BUT they dont fit in the frame holes for a 69-72 the 67-68 have smaller holes in the frame

Hmmm didn't know that.. Seems they market them all the same.

So if im using a 71 frame do i need cushions for a 71 or will they make the 67 front clip sit too high ?

Use the bushings for the front clip your using.The bushings will fit your frame,67-68 are diff from 69-72

Wont the frame holes on the 71 be too large for the 67 bushings ?

[72MARIO]

Yes. You will need to weld the holes up to be smaller in order to use the 67-68 mounts.

Okay - let's settle this one for once and for all.

I know the diameter of the 67/68 bracket is smaller than the 69/72 bracket. I have not seen any difference in the mounting area of the different year core supports - i.e. built up or stepped down or anything. I also have not noticed any difference in the placement of the brackets between 67/68 and 69/70.

That's not to say there isn't any difference but I just have not seen any.

I believe you should use the correct bushing for whatever frame bracket you have.

If anyone knows of a difference please post it here. This has come up before and I would just to resolve it so we don't have to guess anymore.

Thanks for your comments and thoughts on this - Bob

the only difference is the thickness of the bushing. the mounting tab on the frame should be the same(at least it is on my 68 frame). The 67-68 mounts just rest on top of tab, thet don't mount like the cab bushings.

I got into this when I decided to put a 68 clip on my 71 C10.
When I start to trail fit-up the clip I kept having problems, that's when I noticed that some vendors make different core support bushings for 67-68 that those for 69-72. I know the LMC catalog shows the same bushings for 67-72. I also have seen the difference between the frame horns for the 67-68 and 69-72, the 69-72 having the larger diameter holes. Do the holes in my 71 need to be welded-up to make a smaller diameter hole, so that I can use the 67-68 core supp bushings which are a thinner thickness if I remember correctly. Regards

YES

The fenders will not line up correctly with the thivk 69-72 core support mounts.
