My 54's frame is different than yours but here are some things to think about.

I see you have a gas tank under the bed, so the shock mounts aren't your only issue to deal with.

My cross sills were damaged (warped, rusty, blown out welds...) so I replaced them with 2x2 square steel tubing. I used riv-nuts where you couldn't get to the regular nuts. I might have used repro sills but shipping is an issue for me - probably not for you.

I cut up some 3/4" hardwood flooring to go between the angle strips and the cross sills while getting everything lined up. C-clamps are useful for this.

Fender location is determined by the running boards.
