1977-1990 B-Body crossmember | RCB3-350

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.

LS engine lift plates

Very pleased with the plates! Easy to attach the hoist and maneuver the engine block. Cleared the truck intake and protected the coils and other delicate bits!
Thanks Trevor

Nice product fit almost perfect

Nicely made required slight massaging for the large bolts to fit through perfectly which the instructions mentioned, but very happy with purchase!

Outstanding Product and first of its kind!

Had the opportunity to grab a 6L80E crossmember for an X-body car, it works great. Fit and finish of the crossmember is very nice and I didn't even have to cut the tunnel. Great product, and the company kept me updated every step of the way! Will recommend to others and use again on future builds.

Cross member and adapterplate

Well made parts looks and feels like high quality materials even the powder coating on the cross member is flawless other then that cant really review parts any further because I have yet to install them on my car. All tho I am looking forward to installing these parts on my car and hopefully it goes as easy as everyone claims.
