Will 17x9.5 and 17x11 wheels fit a 73 duster?

I think your math is goofy.

My BBP 7.25" rear was 56-5/8" drum to drum. A 68-70 B rear is 60 1/8". Even with 1" spacers, you're at 58 5/8". So, 60.125"- 56.625 =1.5" , divide by two and you get .75". So, the B body rear is going to be .75" wider, per side, than your current set up with the spacers.

I haven't measured the width on a SBP 7.25 though.

Yes that math is way off not sure what I was thinking
You are right
I need to remount wheel and measure with more than my calculated eyeball. (will do this tomorrow) and report back
May one day just unbolt current rear end from springs and toss tires on the b body rear i already have and roll her under to see how clearance is.

I definately need to cut the fender lip tegardless
