Here's a pic of the melted plastic portion of the hydo clutch line. stupid plastic lines that GM ran right over and next to the exhaust manifolds and EGR feeder tube.
After striking out at a local-ish hot rod shop that thought he had the roll pin to -3 fittings, I decided to re-use the components from the '88 SM465 setup. Everything was new from last year, I just had managed to kink/break the hydro line at the slave cylinder. No problem, I got a 12" piece of M6 brake line and a union fitting, re-flared the hardline and re-bent the hard lines so that I could route them as far away from the exhaust manifold as possible on the passenger side. I read a few threads about the older style hydraulics not working with the NV4500- I don't know why people seem to think that, they worked fine for me tonight. After comparing specs of the master and slave cylinders, the masters both have a 19mm bore, the bore of the slave for the '88 is .060 ( 1/16th-ish of an inch) larger then the one on the 1 piece sealed unit. I may have lost a
TINY bit of pressure from that, but I honestly couldn't tell any difference. The release point was about mid travel of the clutch pedal, same as the "correct" hydro system. I will just keep this setup unless something terrible happens.
My $6 repair solution instead of shelling out $80 for a new line.
Everything seemed to shift ok, no melted hydro lines tonight. After driving the SM465 for so long, it feels a bit weird shifting into 5th gear. I have 3.73's in the axles, so it will be interesting to see where the RPMs at 60 mph once I get the needle gauge swapped into the dash. I'm not a fan of the moonie gauges.
