Raidmagic T56 into an early C-4 swap questions

Hey guys. I just made a deal on a wrecked 2000 WS6 Trans Am today. My main target for the purchase was the transmission and it's parts. My question is can I use the clutch master, slave and all from the Trans Am? I have pedals already from an 86 4+3 car so I'm hoping I can use all the parts from the donor car. Also what to do about the C-beam. I know someone makes an adaptor but in talking to -=Jeff=- he said it wasn't a real good piece. Anyone with experience? Jeffvette I guess bought one and redid it better.
Any advise you can offer would be great. I can't wait to get this 6 speed behind my LS1

Those guys have a T56 conversion for the c-beam.

At this stage, you use all LS1 parts for the clutch... There is just no reason to so anything else. What I don't know is if you will need to mod the floor pan, but I doubt it. You may need to move or enlarge the shifter hole.

Looks good, thanks for the link. It's a good price too. I'm sure I'll have more questions when I get it all apart

You're definitely going to have to cut up the center console for it.

Stay away from offset shifters, they are junk.

Also, don't the fbody masters have an angled bolt flange? Maybe there's a C5 unit or universal unit that fits with less work. Or if the C4 master is the same bore, try that.

The F-body masters do have an angled bolt flange, so they aren't a direct bolt in for a C4. I don't know about a C5 master, it may work out of the box.

It looks like the C5 clutch master is straight...

You may need to modify the shaft length, tho...

Also, check racing supply for like a generic Wilwood or something of that nature.

Will I have a clearance issue with the slave and my headers? Why does it matter the master is angled, will it hit the firewall?

What I like about the store bought conversion is the additional cross brace. Not that it can't be added here...

I like that one Bogus posted. I'd rather cough up a few bucks than spend the time working out all the dimensions of one myself.

Anyone with an idea on the slave and header clearance?

no idea on the clearance... It makes me wonder... I know the LSx motors are more compact and do sit farther back in the engine compartment. But the master cylinder sits to the left of the brake master, and only marginally lower. I would be shocked if the headers were that far out.

I went looking for a right angle mount for the master...

I know they are made; I have seen them in the past, but for the life of me, I can't find one on the web!!! And I wonder if it would really help.

The master isn't my header clearance concern it's the slave. I read somewhere else someone was selling a T-5 and modded headers for the slave.

hm... the slave, I thought, was tucked inside the bell houseing?

Why not get a hydraulic throwout bearing?

I guess at this point instead of guessing I'll just wait untill I get it out and in my hands and see exactly what I'll be working with. I just don't know enough about them to guess on how they are put together.

Hydraulic throwouts have a lot of advantages... not withstanding, less parts.

Can you explain the Hydraulic throw out bearing? I'm not real versed in anything standard shift. Is there different needs to run one other than the normal clutch master?

Stock style C4 T/O bearings are actuated bo a clutch fork, it's in contact with the throwout bearing that presses on the clutch plate. The fork sits on a pivot and goes thru a hole in the bellhousing where attaches to the slave cyl. The slave pushes the fork which pushes on the T/O beraing.

A hydraulic T/O bearing is a one piece assembly that uses the hydraulic pressure to push directly on the T/O bearing eliminating the slave and clutch fork.
Similar to this:
