Master brake cylinder information -

I compared the 3000GT SOHC 1" master cylinder to my '03 Sport and my big '97 Sport this morning. They look identical with the exception of the fluid reservoir. I think the push rod depth is different between the Sport BMCs and the 3000GT BMCs. Anyway, it looks like all the Gen 1 Sports came with 15/16" BMCs. At least that's what the FSMs say.

On a positive note, the 3000GT BMC fluid reservoir doesn't interfere with anything and isn't in the way on either the Gen 1 or Gen 2 Sports so if the BMC fits, there wouldn't be any need to change reservoirs. I checked this on my '97 3.5L and '03 3.5L. I figured if anything was going to conflict, it would show up on the 3.5L.

I'm going to see if I have a spare Sport BMC so I can compare actual measurements.
