[Jack 34pu]

I'm in early stages of buiding an AV8 pu ('50 Merc flathead) and the rear axle will show. I have a Ford 8" rear but it's pumpkin is off center - 9" way to heavy. What open drive banjo rear would fit the A pu and keep the wheels under the fenders? What spring would center the wheels fore & aft as well as bring fender down to tire height. Any tips on an AV8 build would be appreciated from those who have done it
