1979 CJ-7 build help

Im currently building up a cj-7 from the frame up, originally had a 258 in it, but was recently given a 4.3 tbi, was wondering what axles would people consider running?....Also if i do change the axles and need to move the perches, i was wondering to get proper angle should i mount the engine first or after the axles? i kinda need the front axle in to get proper clearance when mounting the engine, ive done swaps in cars before but nothing from ground up so im kinda new to the jeep swaps. any advice will be helpful, ill be posting pics of the build as i can. thanks

Axles aren't determined by the engine alone. Tire size, intended use of the vehicle, and driving style all play a part, among other variables.

Mount the engine first keeping in mind firewall clearance, cooling, driveshaft clearance, and steering parts in mind. The axle is about the last thing you need to worry about in relation to the engine placement. It's not a car and there should be plenty of room regarding the axle.
