Installing a ax15 from a 91-92 cherokee into my 88 wrangler. Already have a np231 w/ correct splines from later yj. The ax15 has an internal slave cylinder or hydraulic release bearing like my ba-10. Wondering what clutch and flywheel I should use or is there any difference? Thanks for any info.

do not use the internal slave bellhousing. finding the lines to go to the slave will probably be a pain in the ass, not to mention how shitty that setup is. that internal slave cylinder left me stranded on 2 occasions. what you need to do is get a bellhousing from a 94 and up YJ, or a TJ bellhousing. you also need a 94 and up slave cylinder, throwout bearing, clutch fork, and this little 2 dollar clip that you can buy from the stealership. your stock clutch master cylinder will work fine with the external slave cylinder. the stock plastic line that goes down to the new external slave will have to be modified to work. i just cut mine and heated it up and it slid right on the new slave.

not to pull a sales pitch on you, but last week i pulled my 1991 4 liter out of my yj to put a 350 in. i had already converted it to external slave, so i have everything you need to convert if you are interested.

Your peugeot tranny and the AX-15 use the same clutch disc, pressure plate, and hydraulic release bearing.
