Cool build.

Since you shimmed the transmission back did you have to shim the slave forward? Should you?

McLeod says you need .125"-.250" for the rxt clutch. I only had .050 without spacers. Adding the .250 trans to bell spacer put me at .300" clearance. I put a .113" tick slave cylinder spacer my friend had left over from his corvette. That put me back at .187.

So, yes, but it depends on what your clearance is.

Wow, the amount you relieved the tunnel to raise the trans is really going to help with the driveline angles. Nice work.

Love this build, can't wait to see it on the road.

Thanks. Surprisingly the tail shaft still isn't as high as the old th400 was. This trans is a monster. If I went any higher, I would have to cut the tunnel all the way to the bellhousing.

I got a plan for the shifter boots. I made another sheetmetal riser to get up higher around the shifter. I don't think I can cram any more sheetmetal inside the console.

I'm going to sandwich a piece of rubber sheet between that and an aluminum hold down ring. I machined that today. I have to find some rubber sheet this week.



For the upper boot, I found a grey universal one on ebay that I'm going to fasten to the bottom of this new bezel that I also machined today. I'll figure out the mounting better once the boot gets here.

I haven't gotten much done in the last couple weeks. I did get the tunnel cover painted, installed and seam sealed. I put a piece of rubber to seal the shifter to the tunnel. I've stripped all the interior in preparation for dynamat (fat mat) install and some carpet pad to try to get the heat and sound down. I also figured out how to make the upper shifter boot attach. It turned out pretty nice and it matches the steering wheel almost perfectly except the steering wheel is a bit dirty. I'm thinking of either having a turbo 6 shifter knob made, or have it engraved in the shifter boot plate, then powdercoat the plate to match the ash tray cover behind it.

Looking good mike! Sent you a pm.

Very nice build. Your fab. skills look great to me. Always liked the GN's. Was that a 90 degree fitting for the clutch master cylinder? The one that is pinned to the end of the cylinder. I have been looking for one due to the proximity to my steering shaft. If so can you tell me were to get one?

[MeanMike]

Thanks. The fitting in the picture is a straight fitting, but I have looked for a 90* fitting before and found this. http://www.ebay.com/itm/84-97-CHEVY-...2c8728&vxp=mtr
They have it in -3 also if you look at their other items.

Nice progress. You're going to need closed cell foam and mass loaded vinyl if you want to block out sound like road noise. Dynamat and the other stick on products are only for vibration dampening. Lots of good info here http://www.sounddeadenershowdown.com/
