My neighbor has a 49 3/4 ton longbed chevy, and he wants me to build a chassis for it. He has a 73-87 crossmember and arms. The track width of it needs to be narrowed 7 inches for the wheels to tuck into the fenders. I've seen a crossmember sectioned a few inches and the center link sectioned the same amount and then sleeved with plug welds. I wanted to section the width of the crossmember and center link 3 inches. Then I wanted to build arms to narrow the c-arm geometry 2 inches, and then trim down the tie rods to adjust those in 2 inches as well. That would remove... 2- 3 -2... 7 inches. Once i have the front geometry narrowed, I would go ahead and build new frame rails like valleycustom did. It seems theoretical to me.
Any opinions on this would be great. thanks.
