For what its worth, the rear end of my 1962 c 30 is sporting a HO 72 which came with the apparently rare 5.38 gears and as I'm not in the stump removal field I went on the hunt for alternate gearing . I've managed to scrounge up 4 more third member's with ratios 5:13 , 4:57 , 4:10 and a 3:90 which I found in a early 50s one ton panel.
I'm in the Toronto area in Canada and am not sure if the 5:38 and the 3:90 gears were more common in this area or if I just lucked out. The 5:38 is the only third member that doesn't have a side thrust adjustment screw.
I'm still running the original 235 matched to a t5 trans with a .72 0/d and have found that the 4:57 works best .
The only flaw in this set up is the lack of park brake which had been part of the original trans. I see where a kit is available for the 9 in. ford rear end to mount a disc on the drive shaft and a caliper on the rear end to achieve a park brake. Has any one tried any thing like that?
