Paul,
Could you look at the rear lower control arms in this thread:
http://forums.performanceyears.com/f...d.php?t=742684
And tell what you think the application was for the arm with the holes? The arm without the holes is the original lower, rear control arm off my 68. The arm without the holes is a used replacement I bought, cleaned, painted. My main concern is "correctness"
Thanks,
John Branson
