Ok, I have some options that are $ generated for the rear axle fix.
1. Fix the Dana 35, with just bearings.
2. I have a wide track set, Dana 30/AMC20 3.31 gears, put both in.
3. Also have a narrow track 30 and 20. The 20 has 1 piece shafts neither has gears.
4. Hunt down a Ford 8.8, they can be found with 4.10's and a decent trac-lock.
Pro and cons of each
1. Its a 35, bearings and possible ring and pinion needed, also a SYE for the TC ($300) Pro's are, I'm not sure there any, besides the wheel lug pattern.
2. Mostly pros, very little cost, can use a Dana 300 (I have one, and it should bolt to the 700r4 by moving 1 hole. The slip yoke is there, and less drive shaft issues. Front lock out hubs and In a couple months I will have 4.10 gears that will bolt right in.
Cons are moving spring perches, and 2 pc. Axles. I also have a lot more CJ axle parts than YJ (basically none)
3. Pros, 1 piece axles. Cons, a lot more work.
4. Pro's, its a stout axle, with the same wheel lug pattern as the current front, and rear disc brakes. Cons, cost, more work, I would need to change from coil springs to leafs.
Thoughts, opinions, possible problems.
Help me out please, Bill
