Just had my 91 MM 4x4 clutch replaced, picked up the the Exedy clutch from Amazon for just under $200. but had a shop do the install as it needed some other work as well. Shop time by the book is about 8 hours so you can use that to figure cost in your area. My flywheel needed to be resurfaced which was about $80. If you do decide to tackle it yourself, I have been told it is much easier with a helper throughout. Good luck which ever way you go!
