This kit has everything, you cut the hole in the fender and weld in the base, I think I'll buy it but waiting on copies of the instructions on how its done. I know some of you hate the idea of street rodding a Packard but thats what I want. the chassie is about finished, Mustang fron clip with power stearing rack&pinion, LS1 Corvette engine, 10 bolt Chevy rear end, etc. I was hoping someone on this list has put a sidemount kit on their car so I could talk to them off list--------Richie
