i was going 2 use a old set of cragar ss for the back section used to weld steele together for the sand rail back in the day i was just wondering about the bs of 6 1/2" on a 10" rim or 8 1/2 on a 12" which is better for 315x60x15 mt dr
thanks

Not sure how close you are, but are you familiar with Weldcraft by any chance?
