Quote: 275 60 drag radials will fit a 7" wide rim and perform well. Not too much bulge and a decent contact patch. And I believe 65 rear ends are a little narrower than 66-67s. I will have to measure, I have a 65 housing in the garage.
Actually, the 66-67 b-body rearends are the narrowest, flange to flange, by a 1/4". 65- 54 1/2", 66-67 - 54 1/4"
