High quality product

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.

B-Body THM350 crossmember

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.
