I will end up welding new plates on the rear. I don't know what rear ratio I want or even what ratio the rear is. I had an 86 Chevy with a small block, sm465 and started with 2.73:1 rear gears and got 20+ mpg on the highway. Ended up blowing the rear diff and put some 8 lug 4.56's. Man she was quick, got to shift pretty fast but top speed was somewhere around 55. I want to be able to cruise on the highway but want to be able to pull pretty good too, so maybe somewhere in the 3.73 range. The plan for now is to figure out the ratio and get a driveshaft made. If it suits then great, if not then start swapping. The front diff is 4.56 so it will probably have to be changed regardless.
