gear question

I have a1978 cj5 with a 304, and I'm running 33" tires with no plans of going bigger. I'm in the middle of doing the yj spring conversion and i bought axles out of 2 different cj7's. The rear is a dana 44 the last numbers on the gear are 43-14, I'm assuming that means its 3.30 gears, the front is a model 30 with gears marked 43-13, so that's 3.07 gears right? Can i run these together or do i need to regear one of them? If so which one should i regear to match the other one? Thanks

Yes, they need to match. I personally would want at least 3.73 but given the choice I'd match the front to the rear and run the 3.31's.

Thanks for the advice, I would like to change both gears eventually, but i can only afford to do one axle now, I just want to get them under the jeep and get back on the road

If you can keep it out of 4wd while you get to that 'eventually' for both axles you can still drive it. Regearing isn't cheap.

I don't think i could keep it out of 4wd, I have a couple trips planned already. Maybe I'll just leave the stock axles in it for now. Was going to put the widetracks in while everything is apart.
