Frame holes

[Robert C.]

On my small block 65 frame there are 4 pre-taped holes, located on each side of the rear frame cross- member. The location is where the big block rear stabilizer bar bushing brackets are mounted. Question; Do ALL 65-67 frames have these holes predrilled, big block or not? Question; Are the holes in the top ends of the trailing arms, used to mount the ends of the rear stabilizer bar brackets, present on all' replacement' standard trailing arms?

By "pre-tapped holes" I assume that you mean a hole in the frame with a weld nut attached on the inside. I did a little survey on this subject awhile back and also made my own observations at random Corvettes at shows. It would seem that a large number of small block cars DO HAVE the holes/weld nuts. However, not all. My 1969 small block has neither the holes nor the weld nuts and I have seen a few other cars without them.

As far as the SERVICE trailing arms go, the last available SERVICE trailing arms, GM #14035663 and 14035664 which have been the only SERVICE arms available since 1983 for all 1963-82 Corvette applications, DO HAVE the bolt holes pre-drilled for the sway bar brackets. There were 3 previous iterations of the trailing arms, though, and I don't know if each of these also had the holes pre-drilled or not.

Re: Frame holes for Rear Sway Bar

Bob --- Is your frame original; ie. have you seen the VIN derivative stampings ? Joe is probably right in saying that a few random 65 to early C3 small block cars have these holes with the nuts welded inside (ie. done DURING frame fabrication), but I would doubt it during the first year for this feature, and there'd be even less chance that it would be found on a car with a VIN earlier than the L78 introduction (late 12000's).

I agree. I should have mentioned that I would seriously doubt that many 65s built much prior to introduction of the L-78 would have the rear sway bar weld nuts. Of course, no earlier C2s would have them.

Re: Frame holes for Rear Sway Bar

Wayne and Joe , My vin is 12,653 so that would put it in the ballpark. I now need to go check my frame vin. I've never looked.I don't look at to much that's not judged. Thanks for the responce, Bob ( There are no holes in my rear trailing arms for the bar.
