In case anyone is interested, I just finished putting an AX15 behind a 2.5 4cy. If you?ve ever considered this swap, but weren?t sure of the issues involved, I?d be glad to answer any questions. I?ll only have it this way for about another 6 months, as I?m preparing to put a diesel in. Just wanted to have all my driveshafts made to length way ahead of time, so I can get it all done in a weekend. Also, I?ll be rebuilding the AX5 that I took out, if anyones interested in it. The NP231 will be available also, as the spline count won?t work with the AX15. (The diesel will ba a Cummins 3.9 turbo)
