Alec,
I'll get you the measurement for the T18 I have. I would have to say that $400 isn't a very realistic figure for a T18 swap. You might find a transmission with the proper adapter for that amount, but that would be lucky. Add on the price of a bellhousing (if necessary), transmission jack rental, clutch parts, gasket seals, driveshafts (most likely necessary), and other incidentals and you're pushing $1000. In the other post, you don't say if you want one with the granny gear or not. I assume that you do. Go check out
http://www.jeeptech.com so you know what you are looking for and what things to expect to run into in the swap. I thought I could do it for around $600 and I ended up spending around $1000 doing all of the work myself. I'm not trying to discourage you because it is well worth the trouble, just making sure you know what you're in for. /wwwthreads_images/icons/smile.gif
