While you’re at it … make a drop out crossmember to tie the chassis together like the stock crossmember did . It is to keep the chassis from twisting from the weight on the front cab mounts . It goes a long way to keep panel alignment .
BTW the GMC version is a drop out type . Find one of those and save a bunch of time .

I still have to cut and modify this one so the 4L60E can be serviced .
