LS7 clutch hydraulics
Thought I read previously that in early C5's if you install a LS7 clutch you need to change out the master and slave cylinder's to a newer version.
I did some searching and can't seem to find that again. I have a 99 FRC and just orderd my LS7 clutch kit from Fred Beans. Do I need to change out the slave and master cylinders?
Thanks,
Rich

Is the following news to people?
I understand from a few searches that for the LS7 clutch (installed in a C5) to have the stock pedal height a shim may be required?
Quote;
"The fix for LS7 CLUTCH/FLYWHEEL in a C-5 is - .1875 shim behind the slave cylinder."
I have no idea if this is with a particular year slave or not...
Something to check perhaps...
This is likely my next mod/purchase so I am very interested if anyone has the experience with this particular issue.

Got it from GM Direct, $100 and also adding the bleeder extensions from LAPD for $85. Will make the call on the clutch when I get it out.

Turns out I needed one for the RAM DD I'm now running in the 402.
