D Winn -

If you need new hardware, I listed original GM part numbers and Fastenal equivalents when I recapped my motor mount installation in this post. NOTE >>> My photo of the underside of the cross member is WRONG because it has the thick flat washers mounted on the bottom of the cross member instead of between the retainer and the cross member.
> My post w/incorrect placement of spacer

As posted previously by DADS50 -
> Bottom view - CORRECT PLACEMENT of nuts and washers. (Denny Graham)
> STAND OFF WASHERS between retainer plate and cross member. (Denny Graham)
> Factory Assembly Manual - poor reproduction is difficult to see placement of stand off washers (GM #365685 3/8" ID, 1-1/4" OD, 0.187 thick)
> Denny's description of the standoff washer
