Basically, none of this info is useful without backspace numbers.
I just measured out how a 235/60-14 would fit on the front of my 67 Barracuda 'vert, based on a 14 x 7 Torquethrust with 3.5" backspace, and the answer is ... not a chance. I'm guessing the Cragars must be 4 or 4.5.
235 is probably wider than recommended for 6" rims. When I looked it up, it said rim width = 6.5 to 8.5".
