| − | A | + | A 1978-'88 Monte Carlo 7.625" rearend is about 0.5" narrower than the stock Buick Special rearend. Other similar G-body rearends should work as well. Lower control arm brackets will need to be fabricated. A jig for the placement of the brackets will be a help in getting the correct angle and spacing. While this differential is not known for its strength, it is stronger than the stock unit, and can be upgraded by using a better aftermarket limited slip diff. |

It has been said that a late '70s Ford Fairmont rearend is almost the same dimensions as the Buick rearend, but its strength may be limited. That leaves some other choices like obtaining a 8.5" 10 bolt with the control arm "eyes" cast into the carrier, or a similar 12 bolt, or a 8.8" Ford rearend (also equipped to use control arms), and then having the housing cut and the spring pads relocated. It has been found that a 1988 Mustang 8.8" rearend is 4 inches too wide, but could work if narrowed. | It has been said that a late '70s Ford Fairmont rearend is almost the same dimensions as the Buick rearend, but its strength may be limited.

A fabricated cable clutch linkage is one option because of the lack of room on the firewall for a clutch master cylinder. That said, there may well be a way to use a hydraulic throw out bearing w/a remotely mounted clutch master cylinder. | A fabricated cable clutch linkage is one option because of the lack of room on the firewall for a clutch master cylinder.
