I have a 1972 240z that I am getting road worthy. All my seals on the brake cylinders are leaking, so I decided to upgrade all the way around. I have the maxima rear disk conversion, and plan to buy the toyota from calipers. I see a lot of people mention upgrading the master cylinder for the extra fluid needed. I was thinking the one that came off the 280zx. Thoughts? Recommendations?

I found this one on ebay (I would just local, just needed an image):

You need the 15/16 brake master cylinder from a 79-81 280zx. RAYBESTOS Part # MC39277-You can get them for approximately $115-$130.00 and not

the $425.00 this guy wants. http://www.ebay.com/itm/Datsun-240z-Brake-Master-Cylinder-4-Wheel-Disc-NEW-RARE-/370528489441?pt=Motors_Car_Truck_Parts_Accessories&hash=item5645380fe1&vxp=mtr

Here's a write up on the conversion.
