Moser Rear to Narrow or not to Narrow?

Here,s how I did mine with a stock A-body 8 3/4
-measured housing end to end 52 5/8
-this would mean a 7.5 inch b.spacing on a 15x10 rim

I had 3 inches removed from each side of the housing bringing it to 46 5/8
-now can run a 4.5 b.spacing on a 15x10 rim

I,ve now moved on to a Dana60 at 46 5/8 and run 15x12 ProStars with a 15x12x29 inch slick(it,s tight,very tight)the slicks buldge to 13.5 inches.My next new slicks will be 15x11.5x29 to be safe.

I had lots of help from Crackedback(Rob)when doing my rear mods.Thanks again Rob.:D
