1963-2001 GM RWD Transmission mount shims are useful for tuning drive train and drive shaft angles.
These shims are designed to work with the late model GM style single centered stud mounts, or the early model GM style dual stud mount with 1-1/2" between hole centers.
The base dimensions of 1-1/4" x 2-3/4" provide a solid contact between the transmission mount and the transmission crossmember. Attempts to use a standard flat washer as a shim will never provide the same contact or rigidity which these precision shims accomplish.
These aluminum shims are 1-1/4" x 2-3/4" x 1/8".
This set of 4 individual shims allow adjustments from 1/8" to 1/2".
Note: Check your transmission mount to assure it has the same pattern dimensions prior to purchasing.
