    I hate4 driving hydraulic clutch setups and was wondering did Chevy/GM ever switch to a hydro-assist in the blazers or trucks of the same era for that matter? Now if i could only find a way to work out my right leg.

    Yeah the late 80's and the 90's trucks have hydro. Before that it's all mechanical. I'm liiking at converting my auto to a manual and with as much frame moovment as these trucks have the hydro is a better set up. The Mechanic set up has a linkage from the body then to a bell crank mounted between the frame and bell housing. There are plenty of stories of the truck getting flexed and binding the linkage.
    Willwood sells a pull style slave that I have seen people make a new inspection cover for the 465 with a bracket to attach those pull cylinders to. Then drill a hole in the clutch fork end for it to pull on.
    Part number on that slave is Wilwood 340-1470

    Yeah you can but those sometimes get into clearence problems on the exhaust. It faces the slave forward. Some you have to make a bracket to mount the slave on.
    Your also buying more parts. You have to get the bell housing, fork and possibly a throw out bearing. For this way all you have to do is drill a hole in the fork and make the plate You don't even have to remove the transmission to do it this way.

    the throw out appears to be common chev part on mine
    didnt compare the fork
    my rams horms go nowhere near the bell but i guess some headers might
    slave is available at any parts store
    if you are junkyard shopping get the bell and fork
    it all bolts up sweet and clean like a factory part should

    whatever you do don't go with a mechanical linkage... with body flex they are HORRIBLE off-road. Can't over emphasize that
