I don't know for sure about your tire/rim sizes? I have heard a common size with the B-Body width rear end is 10"wide rims with a 5" backspace  in a 15" rim is 295/50/15 and that it does fit.
I found this web site to see what your tire diameter is?
http://ejelta.com/tiresize/index.html?ws18=1&tiresize=295%2F50-15&minwidth=&maxwidth=&minratio=&maxratio=&minwheel=&maxwheel=&maxdelta=2
Looks like your tire is 28.81 tall. The 295/50/r-15 is 26.61"
So I don't know....?
Sorry wish I could be of more help?

It depends on which B body rear end is used.  The 66-67 rears are narrower than the 68-70 rears. With a pre 67 rear, 5" backspace fits best. With a 68-70 rear, the 5.25" may work best.

Should fit.

However, tha'ts one hecka of a tall tire.  What's your rear end ratio?  That tall sucker will affect that for sure.

How about a 305-40-18 (if they make such a tire)?
