2five22 Run from anything with an AMC model 20 axle, unless you have the cash and time to either convert them to single piece or replace them with an off-roadable axle like a Dana 44.

NHflannelman12JK76CJ5 I've got a 76 with a Dana 30 front and AMC 20 rear, unsure what the gears are but I've heard of folks running 33's on them and them holding up fairly well. If you're not doing heavy wheeling, you should be okay.

You can pick up used axles on craigslist fairly cheap if you're prepared to do a bit of work (better than buying Dana 60's or 44's brand new $$$, well, depending on the application, of course).

Rusty Knutt Or YJ four banger and drop inline six in..

Rusty Knutt CJ.. find some Wagoner axles...Dana 44 from an automatic trans have 3.73(I think)
Outboard the Wagoner springs and go go go.

harleydragon yj would probably be the easiest to find a 4.10 since you could use 4 cylinder axles

bigdog9801 OK - so i guess I could find something to swap in without re-gearing. I don't really do much off-roading so I'm not super concerned if I blew some axels. Plus if they were something I could just swap in I would be much more comfortable.

I'm looking at what I should do for my next project.

Its either a YJ, CJ or 64-66 mustang.

4Jeepn You might be able to swap in axles with lower gears from a 4cly CJ, but I am not sure what gears they came with. You could not use the front YJ dana 30 as the diff is on the wrong side.. Perhaps consider J-trucks from the time frame.

harleydragon if you have to buy axles anyway you might want to go with full size axles..they would handle 35's with less chance of failure

bigdog9801 I'm assuming I would have to put new axels in (or re-gear the existing). I guess my question is, will it be easy or difficult to find properly geared axels to put in. For example, I believe for a YJ you can put in the axel from a 2.5L into the 4.0L to get the right gearing.

harleydragon depends on the gear ratio it has..I have a yj and a tj with autos and really like them

1977 CJ7 Questions

I have been looking at another Wrangler to buy, and wanted to do a 6 cylinder YJ and put in an SOA using axels from a 4 cylinder (4.10 gear ratios) to fit/run 35 inch tires.

I have however been side-tracked by a 1977 CJ7 6 cylinder auto.

My question is, can i still do this or will I have to pay to have the axels re-geared. I don't want to take on more than I want by mistake.

Any other limits to this idea would be helpful to be aware of as well.

The auto is interesting to me as well because then my wife would be comfortable driving it.

Thanks.
