I've started to swap in a narrow track 44 into my 79 CJ7. The 30 up front will need diffrent gears. I was thinking of using the front gears out of the doner '73 cj5. They have the same tooth count as the 44. The gear swap sounds a little tricky but I'm going to have a go at it. Can I use the gears out of the '73 dana 30 front? Anyone got a good place to get the 2 3/4 spring perches for the 44?
