AX15 external slave conversion from an internal

I am collecting all the needed pieces to convert my 4.2 AX15 internal slave to an externerl. I have the bearing retainer and just picked up a XJ bell housing with the fork and pivot ball. If I get a slave cylinder, master cylinder and hose for a 1995 or 96 YJ will that all bolt directly in, no mods? Also will my dust cover plate from the internal slave bell housing work with my external bell housing? I know there are tons of write ups on this but I am putting a lot of time and money into this conversion and don't want any last minute expensive surprises. Any advise will be appreciated. Thanks Jim

Yes the master/salve from a 95 will work. I think they were the same until 99 or 2000. Yes the dustcover is swappable.

Yep that's exaclty what I did on my '90 4.2. The 95 slave/master will work but some you have to drill out the hole on the end of the master push rod to fit over the clutch stud its plastic so be careful . Also on some the bolt pattern is diffrent on the master so what I did is drill the flange to fit the existing bolts in the firewall. Other than that what clutch you getting? If your unsure of its condition it might be a good time to replace it too.

I plan on putting in a new clutch the one in there works fine but at this stage of the game I'm not going to cheapen out. Thanks for the info.

I'd replace the flywheel too.
