Dana 300 in a 98

Sitting around thinking about stuff (I know dangerous) and thoughts of course went to my Xj. I am going to start my lift and axles in the very near future. Instead of wasting time with a SYE, why not install the Dana 300 I have sitting in the garage? I have heard rumors that a 300 will bolt up in place of a 231 in a Yj but what about a 242 in an Xj? The other issue I came up with was shifters. I would like to twin stick it but I dont want to cut up my console and honestly the more I think about it if I can make the linkage work with my stock shifter I would rather do that. I will be flipping it so it will become driverside to line up with my Dana 44. I am not against a hack and tap in the 241 or salvaging the SYE 231 I have in the Yj but I was thinking a nice cast case and gear on gear would hold up better than an aluminum chain driven case. That being said, I have never hurt my 231 (behind a t-18 and a 302 right now). Thoughts opinions concerns?

d300 = passenger drop

I know I will be flipping it (running it upside down).

You will need to run cable shifters to flip it.

An early model Bronco D20 will work with a 23 spline input shaft from AA, and the J pattern ones with run twin sticked like a D300.

Yes it will bolt up but not clocked properly, the single offset bolt is at a different rotation. Get a clocking ring. Yes, you have to run cable shifters out the back to clear the front driveline. Or do a flip kit where the shifting rods are moved up top. Here 's some info you might be interested in. http://naxja.org/forum/showthread.php?t=1073212

Nice!!!!!

I have a box 4 rocks 231/d300 but you can flip a d300 without a clocking ring. you will have to oval out one of the holes on the trans output but whatever.

If you're creative you can rig up mechanical shifters or run cable shifters (I have the nortwest fab triple stick).
