How about narrowing it so you can use the axle tube for the perch(es). You could always cut into the center section a little to expose more useable axle tube. That would keep narrowing to a minimum.
That is what I did for my Chevy 60 for my MJ. Worked well, if ya want it narrowed a bit. Narrowed front would match nicely with a C and C 14 Bolt rear.
