Rear wheel Drive Chevy Frame Mount Chart

These are Original Part numbers from a 1983 GM Parts book. Some numbers are discontinued or replaced with new numbers. Don�t assume that GM no longer stocks parts for older cars. Many parts are still in the parts system and retrievable if you have the correct part number. A good relationship with a knowledgeable GM parts counter guy will help find seemingly obsolete GM parts.

Many GM chassis parts will fit other cars within chassis family groups:

F = Camaro, Firebird

X = Nova, Omega, Ventura, Apollo

A = Chevelle, F-85, Cutlass, Special, Skylark, Tempest, Lemans

B = Caprice, Bonneville, Full Size

G= Monte Carlo, Grand National

H = Vega , Monza

T = Chevette

Y= Corvette

Some later subframe equipped cars never came with a big block but by using earlier mounts will make it a relatively simple "bolt in". Note that these are only the Frame brackets. At least three different engine side rubber mount PN�s are also available.
