Chevelle & Ford Rear End Widths

CHEVELLESTUFF

Lower spring mount on 1966 Chevelle.  A bolt and plate arrangement hold the spring in place and the pigtail is the same general diameter as the rest of the spring.

CHEVELLESTUFF

Lower spring mount on 67 and later Chevelles fit over a tower on the rear end and the pigtail is a smaller diameter.

It has been reported that the 1967 model year could have either type of spring mount but I cannot confirm this

Casting numbers found to be the most prevalent in Chevelle 12-bolt rear ends:

1965 Chevelle 3859140N
1966 Chevelle 3875745N
1967 Chevelle 3894939NF
68-69 Chevelle 3917124NF
1969 Chevelle 3959038NF
70-72 Chevelle 3969278NF

As always, there will most likely be some rumor of overlap in numbers but unless you have a build sheet/protect-o-plate and can verify the stamped codes as original, who knows? It should also be noted that the 1965 12-bolt is the only one with the diagonal bracing on the center section casting.

Note: Thanks to David Bates for the above information!
