So, I think I mentioned before that I ended up with a C5 torque tube and C6 bellhousing. It was supposed to all be C6 stuff, but whatever. Since I'm deep into this torque tube due to the custom length and Driveshaft Shop custom propshaft, I'm not going to swap that out.
The issue I found is that the clutch hydraulic stack up was problematic, with too tight of tolerance between the slave and pressure plate (insufficient air gap). I originally had WAY too little gap but that was due to the C6 hydraulic setup I originally bought. Went to a C5 slave and my stack is VERY close, but still a little too tight. So what do I do? Well, I -assume- a C5 bellhousing would solve it, but that's annoying and expensive. So instead I measured the alignment dowels and found them to have >3/8" of engagement. Same with the input shaft to bearing pilot bearing (plenty of engagement). So my solution?
3d scan the mating surface and model a small spacer to push the gap out 0.125" to get my gap right. I did a quick scan, modeled a spacer in CAD and 3d printed a mock up. Gotta love 3d scanning, because the spacer literally snap fit into place on the dowels. I ordered up a couple different thicknesses from SendCutSend so that I can dial it in perfectly, but this should solve the issue and not move the rest of the drivetrain back enough to matter for my purposes.
This stuff is why these projects take forever...
