Elusive 1978 280Z MC caps

[dmorales-bello]

I want to replace the aged master cylinder caps on my 1978 280Z. Since that was the first and only year for the fluid level sensors in the S30s MC caps, there don't seem to be any NOS replacements that I can find. Can't locate any references on this forum either.

Several options have come to mind: NOS caps (have not been able to find any), using a ZX cap (fitment?), taking the stock ones apart and re-plating the metal cap only, using a previous years' Z cap and transferring the sensor mechanism (don't know if they will be compatible), using billet cap covers (but the ones I've located don't seem to be specific for the 1978 MC).

I would appreciate any experiences along this line.

I have MC caps with the level sensors.  They are off the 15/16" ZX MC.  I think it's an '81.  I'm not using them.

Would these fit the '78 280Z? Is the finish on the caps in good shape? If so I would be happy to buy them from you.

Sorry for the delay.  I think these will fit your car.

No problem at all. Yes, those look a lot like mine. Don't want to be rude or anything but mine are actually in much better shape with just a bit of corrosion on the finish. That's why I'm trying to either find new compatible ones or figure out if they can be taken apart and re-plated. Thanks so very much nonetheless!
