C2: 66 upper/lower pivot shaft washer part #

[Gary B.]

Can someone tell me if the large concave washers at both ends of the
upper A-arm pivot shafts are the same part number as the washers
at both ends of the lower A-arm pivot shafts? The number I have for the
upper washers is 3714369 which GM still sells. Is this correct for the
lowers as well?

Thanks,

Gary

No lower is different p/n. Look in your AIM *NM*

The GM #3714369 is the part number for LOWER bushing retainer (washer). It is still available from GM. This is a convex retainer with a 1-13/16" OD and a 7/16" ID.

The UPPER bushing retainer was originally GM #3710586. That part was discontinued over 20 years ago and replaced by GM #9785742. The GM #3710586 was 1-53/64" OD and had a 3/8" ID hole. The GM #9785742 has a 1-25/32 OD and a 3/8" ID hole.
