This isn't on my Blazer, but on an 84 K20. it got an SM465, and the clutch fork came out...from wha tI understand, its supposed to have a shaft between the two "prongs", and it slipped off. The part that swivels to engage the fork (mounted to the frame, tranny, and attached to clutch pedal) was messed with by the previous owner, and we took his junk off, and welded on a new piece, but its a little differrnt from stock. Instead of being straight, it has an angle in it, and the hole is a little out of position. Could this be the problem? What would be involved in putting the fork back in? Thanks, sorry if this was vague.
