    I have been looking at different routes to take for an axle swap. Is the WT Dana 30/amc 20 the easiest swap? I found a set of scout 44s for $250 but I think they will take more work/money to get in. Seems the same for Waggy axles too.

    I am not to worried about bombproof strength. This will mostly be a beach and cruising rig. I will be running 35's and keeping axles open.

    Does the 30 drop right between a 2a, or is the diff placement in the way of spring perch? I can't get an accurate measurement with the one on my cj7. Thanks

    What are you running for a transfer case? If you still have the model 18 the AMC 20 won't work because of the offset rear driveshaft.

    I will not be running the Dana18, I already pulled it and will use Dana 20. I am still in the air about which tranny, maybe a t176. It's a shame because I have the Husky overdrive that would have been good to use. The jeep will be remaining soa also.

    A good option, but not cheap is to run a high pinion axle like a D44 or D60 in the rear (front end cut, new outers, re-tubed). Combining an SOA on such a short wheelbase your rear shaft will have quite an angle. Additionally, the D20 rear output is much higher then on the D18. the d18 drops the output to the right and DOWN. The D20 is straight back, and no drop.
    I swithed to a D20 on my ECJ5, and the rear driveshaft angle is a bit steep. I'm gonna lower the height of the t-case mount so I get a better rear angle. Although I know that will have an opposite effect upon the front output.

    Anyways, that's my 2 cents.

    I considered that also but was trying to go low buck. Won't a cv shaft help enough with angle issues?
    Can I still use the factory 47 crossmember or do I have to use another?
    Thanks

    You could run an axle from a Quadra Trac Jeep the pumpkin would be offset so you could run the model 18 transfercase. A CJ Quadra Trac axle of course would be a narrow track but you could run wheel spacers or use a Waggy Quadra Trac axle.

    Yes a CV shaft will help with the drive line angle issues. You'll need to change out the rear yoke on the 20. Certain front Explorer and Cherokee drivelines can be picked up at the junk yard shortened and balanced for a cheap upgrade.

    Yup, I have a tom woods 1310 yoke for the 20.

    I will most likely go with the WT 30/20. What I should do, is buy big boy axles for my 86 and use the 30/44 from that.

    Anyone know at what degree the perches should be welded at for an soa with 2" springs? .........yes, it is tall.

    The easiest will be a axles from an intermediate CJ (1972-75), with a centered flanged Dana 44 in the rear and open-knuckle Dana 30 in front. With these, the spring pads are in n the right place and they will bolt in. I would avoid the M20 (AMC 20, the Corporate 20) - it's a throw-away axle for serious builders, and the spring pads will be in the wrong place. They are cheap and available because of their their terrible reputation, but that reputation is deserved.

    I would also downsize from 35s. IMO you're only buying them for appearance over more conventional sizes (ie 31-33s) with the build you've described. And skip the spring-over.
