Morrison makes a triangulated 4 bar with an entire subframe. This comes with Shocks, sway bar and rear end housing (9") for $3650. Its a nicely engineered unit.
My chassis guy (Ed Lapadura, Boots Performance) says we can build it for less. This would allow me to keep more stock sheet metal, trunk/wheel well, rear passenger floor than with the aftermarket.

I want to keep my Dana 60, too, as this is a Mopar.

I will have over 16" of wheel well to accommodate. also a Diameter of up to 29".
This leaves tire choice up to cost as its a wear item. A 315/35/ZR20 is about $450 from Tire rack. it is 28.7 in Diameter. I may prefer a little taller sidewall so 18/19" rims are an option.

I will have to consider wheels quality of construction since existing engine dyno'd at 650 and I am running a stick.
Jeff, I'll look at the construction of the Summit rims. Seems like Forgeline/Budnik/Billet specialties have some nice options.
