HR Parts Anti sway bar
 

Anyone out there with a HR parts anti sway bar on a 64-67 a body? The area on the crossmember that the tabs for the heims bolt/weld to is not flat at all. Any pictures would be great and info on what modifying you had to do to the crossmember if any.

Here's a shot on my '65. Due to the nature of the spherical bearings, as long as the mount is secure, the bearings will handle imperfections in the angles. Just try to get the alignment close to straight in line with the bar end.

Thanks for the picture. Your frame looks a lot straighter and flat compared to a 67. I wouldn’t think that there would be a difference in frames. When I fit the piece that bolts to the crossmember there are spaces with 3/8” gap. Try to hammer and dolly this or fill it in with weld?

I would probably try to shim it with washers. As long as it's securely mounted, the aesthetics aren't really important.

Shot of mine…71 gto. It wasn’t particularly flat as I remember, but I was able to mount it..
