Early A Body upper control arm bushings.

I'm rounding up parts to rebuild the front suspension on my 63 Dart Pro Street project. I'ts a back half car with 14.5 x33 slicks with ladder bars. Plans are for a stroked small block bracket car but one day may be converted to a street cruiser. I have donor lbp disc off a 75 Dart complete with upper control arms,non power assist master cylinder and porportioning valve. I also have a v-8 center steering link and larger 11/16 C Body tie rod ends. I also have new upper and lower ball joints. Haven't decided on upper control arm bushings yet. Do I need offset bushings or OEM style. Should I use poly or rubber? After blasting and welding on reinforcement plates I installed OEM rubber lower control arm bushings. Thanks for the help everybody.
