I would pull the adjuster all the way off start the veh in nuetral warm it up,shut it off and start it in gear and give it some gas and see if it slips? I run a petrowork's puk type clutch in mine you might be able to get by with just the disk if you switch over to that type. you will prob. have to open it up and look :-/ there not that hard to do the stuff is light weight easy to lift if you don't have a transjack but you can rent what you need we have a shucks here and they rent or loan the tools you need and the guy's at the auto parts might stop by to help you put the pressure plate back on for a few buck's.
