Rear axle upgrade from SBP to BBP

69_340_GTS said
Just went thru this on my '69 Dart. Assuming this is an 8.75" rear end, with 7" wheels you'll need 4 3/8" R.S., with 8" wheels you'll need 4 7/8" R.S. Of course every car is slightly different.

RS = rear space ?..
Would you happen to have photos of what your vehicle looks like with steelies ? Thanks for good info
