SHOPTALK
See the G Force Crossmember Overview for more info.
For vehicles originally equipped with 3/8″ crossmember bolts, open existing holes on the frame to 1/2″. If you prefer to retain 3/8″fasteners, upgrade the installatin hardware to Grade 8 bolts and hardened flat washers.
Some minor contact between the floorplan and the crossmember may occur due to body bushing settling and deterioration, or a bowed floor pan. Usually, this is not a problem. A hydraulic floor jack with a wood cushion will correct a bowed floor.

Fit great in my 84 Delta 88. Had some issues but G Force made it right and I'm happy to recommend them to others!
Thanks so much for the updated review. We appreciate it and are glad your happy with the replacement part. We try hard to prevent things like this from happening and we're pleased to have had the opportunity to make it right.
Best of luck on your project!

Fit perfect in original mount holes In my 1979 caprice, easy to install, looks and work great
M
I had to drill additional holes inbetween the already made holes because I did not want to use the supplied transmission mount. (I slid the crossmember foward to use regular energy suspension mounts). Quality of the product is superb. Only thing is, the rectangle piece on the driver side is about 1/2 inch too long on both sides. (Theres a lip on the frame rail that doesnt allow the crossmember to slide all the way to the left, as well as it will interfere with the brake line going to the rear). These issues is only because I didnt want to use the supplied mount! I highly recommend. The car installed on is a 1977 caprice aerocoupe.

Quality piece, perfect fit. A little pricey, but paid for the convenience. Was happy there was something for the B-Body, Buick Lesabre, in my case.
