1980 CJ7 offroad build advice

The Jeep as it sits...

258 engine
Stock axles
Stock Tranny and Transfer case
The grill, hood, firewall, and tailgate only remain (rust had its way everything else)


The future plans are strictly offroad only. It will see rocks, hills, and mud. What axles should I use to run 38s and bigger (I was thinking a FF 14 bolt for the rear)? Should I keep the leaf springs or switch to coils or something else and how much of pain is that to switch over? What would be the best trannsmission and transfer case combo? The front axle is a passenger side drop but would it be beneficial at all to switch to a driver side drop as far as the tranny and transfer case go? Should I stretch the wheelbase in the rear to help with driveshaft angle?

I would like to keep the 258 cause I have propane kit for it and I have heard that 258 is a good offroad performer. If I am wrong please let me know. Keep in mind that this a budget build not some high dollar rig, I will rebuild the axles and transfer case myself and will be doing any fabrication needed.

That 14 bolt will be plenty for the rear, but most guys "shave" the chunk or machine a portion of the bottom of the chunk for ground clearance...they are huge apparently. For the front I'm thinking a dana 60...and to clear 38's maybe SOA, inch of body lift and a comp cut on the rear of the tub and tubed feders in the front...unless you've got the budget to link it Don't forget gears, lockers, highsteer, driveshafts, and brakes. I want to do the same to mine
