Hi guys everything is nem and put in by a shop that does them things and been double checked. there thoughts are like nashville 68birds and his problem sounds a lot like mine. It had a 246 gear non possie and from what I read it woud'nt except much of a lower gear so I put a 73 nova 12 bolt and had the mono leaf springs perches welded back on and have had them rechceked for angle and there fine every body seems to be mistified why its beter with the angle being way on the plus side for the pinon gear thanks for any help. Joe PS the factor bars that keep the rear end from rolling up to much, is there supposed to be much of travel to the?
