Rear axle assembly - reccomendation?

This is great info...it's a matter of offset, right?

Any leads on where to learn about A-Body Duster/Demon/Sport wheel wells and what offsets might best accomplish this?

I'm not sure if this is going to help me that much anway...I really want this car to look like it could be a daily-driven car from the mid-70s. No modern looking wheels for me, thanks. Perhaps a set of correctly widened OEM steelies would do the job?

I HEAR YOU! I have not had any problems with mine so far on the street behind a 440. You can get a tracklok and the gears and disks from a 90's Cherokee and throw them in a 8 1/4 carrier if you want. You can get the rears all over the place and just have to look at the ratios. My 3.73 came out of one. Hope it helps.
