I messed with the clutch assembly and brackets some more, and have got things right where I want them and without contact with the steering column . Tomorrow'* adventure will probably be mounting the clutch master cylinder

Great project! Not something that I would do to mine... but it is interesting to watch and see if/how it works. Hopefully very well...

The bottom bracket (in black) is in the way of the clutch master cylinder :? . My bad. I need to redesign in but it seems it would be okay if I flipped it. You can see one of the wire harnesses up there too, and that'* in the way as well. Mounting this may be a challenge considering that it usually just clicks into a hole in the firewall, and my clutch pedal assembly-firewall distance is different, AND, I don't have a flat area there for it to click into

New progress:

I decided to go with using a bracket to mount the master cylinder to the clutch pedal assembly. I figure this is easier than trying to mount it to the firewall at a 45 degree angle (the way it has to be in relation with the pedal assembly). I'll then cut out whatever part of the firewall I have to to get it to fit. I'm having my amazing machinist, Pat of Backdoor Machining do this. He'* like a mechanical genius and can make precisely the right bracket I need. He made a drawing of what he thought would work well and I wish I had it to post it, but you'll be seeing it soon.

After this, I'll be messing with the flywheel and clutch situation. I visited Clutch Dynamics in Lansing and gave the gentleman there a summary of what I'm doing. He said I missed the main guy (another Pat) by a few minutes and said to call or come back tomorrow, but he said my project wouldn't be a problem at all and they do similar things like this including with Fieros.

That'* it for now

I visited my machinist to check his progress. He'll have it done early next week, but he'* a genius (sorry for my crappy photo angles)

My machinist has been busy but should have my clutch pedal assembly done by next Monday (my birthday)

I lifted up the L67 to mess around with the passenger side motor mount. On the L67 it'* located under the harmonic balancer, but with the LN3 is more underneath the air con compressor. The bolt holes are in the same location between the two blocks, and the LN3 bracket and mount will bolt up just fine. I have to pick up a new hydraulic mount cuz it'* leaking and I'm certain it'* "done". Pricey little buggers though, $166 at Advance. Is there a solid mount for this that you guys have used that may interchange? I'll post pix later.

For the heck of it I did some rough measuring of the location of the driver'* side mount that'* attached to the tranny. They're in the same spot, if not very close, between the F40 six speed and the 4T60. I was gonna go ahead and pull the subframe/engine cradle but I need a 6 point 15mm socket, which I don't have at the moment.

Pix later!

This is what I wanted to hear. Watching intently.

When you say the mount is under the HB.. you are talking about a W body motor mount, correct?

The H body mount is on the front of the motor.
