Description

• 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.
