That is the cap from a 90 ZR-1 and all other L98 cars from 90 and earlier, I'm not 100% about the "earlier", but I know it's a 90. The newer master cylinders had a master with one large reservoir versus the 90 that had two small reservoirs. I'm just not sure when the change was made to the one large reservoir.

This seller has it, we also have it in stock, but a bit more $ than this.

It's GM part # 10159854

Awesome! Thanks for all your help. Its just that I ordered a replacement from CA and they send me something a little too small, and i try again and I get the same thing...and I wonder, is it me? I mean, I can read and I know my numbers....where's the problem...? Oh well. Cheers.
