    Hey Grumpy, got my first look at the clutch fork condition after I pull the old engine today. It looks like one of the tangs on the pivot ball retaining spring clip was broken off (missing). It was that way before I removed it so I assume it got damaged in a past clutch replacement. How big a deal is this? The rest of the fork seems to be in good shape.

    it will probably work in that condition but there will be a tendency to put pressure on the throw out bearing slightly off center , or for the fork to pop off the pivot point, so Id replace it as they are fairly cheap and easy to get rather than deal with what might be a future problem.
    be aware theres several types of clutch forks, different lengths and different connections and REPLACEABLE CLUTCH FORK SPRINGS that can be replaced with a RIVET on some versions, Id suggest taking yours to a chevy dealership parts department, so you can have the parts guy supply you with the MATCHED PART, and/or ordering the replacement spring or the whole fork.


    BTW you simply drill out the old rivet , place the new rivet thru the spring and fork , heat it with an oxyacetylene torch from the non-spring side of the fork, place the spring side of the rivet on an anvil for support,and a good whack with a hammer and punch flares the red hot rivet , firmly securing it, any machine shop can do this in 5 minutes if you don,t have the tools or skill required or you can buy a new fork, all that spring install work, takes is a few seconds , just don,t heat the spring , just the rivet.

    keep in mind theres three common throw out bearing heights and youll need the correct height for your particular application to get proper clutch function
