Is the Master Cylinder ZR-1 Specific...
 

I can't find one for my 92 that looks like the one that is on it with the Sensor mount for the fluid level. Are they ZR-1 specific? According to the FSM you can swap the resoviors. So, I already have a slightly used 92 MC...can I swap the resoviors and slap it on there?

What does your 92 one look like?

I know the 90-91 MC are the Same as the L98 car. I also know the 89-91 MC are junk pretty much. My 89 has one from an Fbody now, works 100x better..

It looks just like a regular 92-96 MC except the Plastic single resovior has a plug-in in the side for a fluid level sensor that isn't on any other MC I have seen (ordered) or have.

They are not ZR-1 specific. There were three different designs though.

90-91
92-94
95-96

As far as I'm concerned the 90-91 MC is a better design in one area. The fluid reservoirs. You can actually get all the old fluid out when you flush the system.

Yep I like that feature over the single reservoir model in the lates MYs. GC
