custom 2.2 wrecker, what leafs would a LHS stock?

[ax10ny]

hey all,

im in the process of building a chassis for a 2.2 based flatbed tow unit. im going to be using axial axles, a rc4wd shackle and mount kit. the chassis is 3/4 aluminum c- channel. way to big but i want the frame to look beefy.

im going to be ordering parts online but would really like to have leafs tomarrow so i can get them mounted up to the axles and kinda get a wheelbase figured out.

so what truck out there (prob a f350 is what i think) would a lhs most likely carry leafs for?
