I hope I'm posting in the right area, I wanna participate. My sweetheart(1964 C-30 Suburban) So it kept popping out of 2nd gear even if I held the shifter down, it seemed like it was gear related as opposed to Syncro related. I have 2 of them and Pop had one he didn't need. Internals Look brand new in there, and it feels beautiful. It's the older model and it didn't have the hand brake. So I swapped out the yoke and rear cover assembly and between the two I had I was able to recreate/build the propeller shaft hand parking brake. Which I had to have the band relined(I hate paying to have stuff done. I don't call a plumber, electrician, or carpenter....ever! But brake lining is difficult because materials and procedures are top secret). Anyhow a tranny swap turned into a clutch, rear main seal, the pilot bearing was stuck like chuck and I had to cut it & chisel it out in pieces. Found out I have a 1980-85' 350ci power plant with all of the 1964 attachments and housings. The person in there before me didn't know there's a pin hole in the crank and flywheel for a reason which causes me some concern. This covid thing has hit us financially and since I hate to have stuff done by someone else I decided to resurface the flywheel myself......go ahead and breath everyone I have a max runout of .003(pretty darn good if you ask me). I mounted the bell housing and followed my 1963 Chev truck shop manual(supposed to be a chev factory shop manual??🤬) Which I find a little confusing. I think they pull engine/tranny when they do a clutch because there doesn't seem to be a procedure for engine in truck. Although there's reference to "use transmission section to remove tranny" in the clutch section?(I accidentally ordered the 1964 shop supplemental for cars and not trucks so maybe it's in there?) By far the most in depth procedure for a clutch I've ever done(on an Automobile. I'm getting to finish driving the pilot bearing home and see if I can squeeze the pressure plate and disc between the crossmember and bellhousing.'m gonna have to rebuild another sm-420 probably end up with 1out of the 2 I have. Does anyone know if syncros are available yet as an aftermarket item? or have any other advice or knowledge regarding the procedure?
