Rear say bar question
Installing sway bar on 1970 convert. Instruction indicate there should
be two holes where white arrows are pointing in picture below.
I don't have holes. Am I supposed to drill holes in top of trailing arms to mount bracket or did I get wrong sway bar for 70 vert.

Yes on drilling the 5/16" holes. That part of the picture is correct.I don't know where you got the picture but it is wrong. You also need bushing at the sway bar itself. I don't see that in the picture. On my '81 the holes were already on the trailing arm but the ones on the frame were well "hidden". After laying out the holes on the frame I noticed a slight imperfection in the paint. After digging around with a scratch awl I found the first hole. After measuring over 2" I found the 2nd hole. Apparantly they fill these unused holes with some type of putty. After cleaning them out I had to rethread with a tap to clean out the thread holes. I was sure glad that I found the holes as I would have had to drop the mufflers. With the holes it was an easy installation. Good luck. Post a picture when done.

The photo is mine. What do you mean the photo is wrong. I found the holes in the frame where the clamp and bushing go, but the instructions indicate putting the brass looking plate on the top of the trailing arm with two bolts coming in from the top. I have a second smaller plate with threads that slides in the opening in the arm and the two plates are then bolted together. Instructions say holes should be there but they are not. Before I drill the holes would love to know why you say the photo is wrong.
Thanks

that helps
Thanks Rich
yours is the same as mine. I was just confused since the instructions indicated the holes were already in. I guess I will have to drill my own.
Thanks for taking the time to help.

Sorry guys, not trying to hi-jack thread but I have heard conflicting statements on rear sway bars and the corvette rear setup . I had one guy say too much rear sway bar on an independant rear suspension will "kill" the advantage of having that suspension?
any input would be appreciated

As to the swaybar install itself....I cant say that thin plate instills me with much confidence. A good sized swaybar will bend that plate over time I think...right at the rearmost bolt.

Secondly: about the above ..."kill" the advantage of having..." statement. Yes. If the rear sway bar is to stiff it will cause oversteer. A long time ago thread was from a forum member who removed his front sway bar and went for a drive with the rear sway bar still attached. He accelerated and changed lanes to pass a truck. His car immediately went into a spin. So I think the idea is that a rear anti-sway bar is good but it can't be stronger (bigger in diameter) than the front anti sway bar.
