It's not too terribly bad. Do you have a shop manual or cardisc? This was one of the first things that I did when I got my 92 spider last year. I am far from an experienced mechanic but can turn a wrench. I replaced both master and slave. (The slave is MUCH more of a pain in the ass.)
By the way, I got the parts from DiFatta Bros.

Its beginning to look like spring in new england. I just started my spider for the first time in 3 months!!!
