This has probably been answered on here a million times but.... do rear lower control arms from a 66 chevelle fit the wider 70 chevelle 12-bolt rear ends? I hope this is clear. Most people say yes but aren't 100%. Please help!!!

Thanks,
Lon

The rear lowers ARE the same on Chevelles from 1964 thru 1972.
It's the uppers that are two different lengths...'64 thru '67 and '68 thru '72.
