3. With the front axle and springs out of the way, I removed the stock front crossmember because it will interfere with the Corvette suspension. Boy, are those a job. Once it is out, the bottom flange of the framerails has a large piece that has to be trimmed off where the crossmember used to mount. I need the top and bottom rails 2 inches wide from the cab mounts forward so the flat boxing plates will fit properly. Chevys are the worst for having a lot to clean up before you can start installing. Fords just need a small trim here and there.
