I can supply new master cylinders as per photos to suit Dodge AT4 and D5N, as well as some International A, AB and C series trucks, some Studebaker, some early Chrysler vehicles, or any other vehicle with this standard tri-bolt mount. I can access 1-1/8" bore (all Dodge clutches, as well as the ute brake), 1-1/4" (3 series truck brake) and 1-1/2" (4, 5, 6, 7 series truck brake)

I will try to stock 1-1/8", 1-1/4" and 1-1/2" bore master cylinders but stock may be nil on occasion because they take 3-4 weeks to ship from the USA and I am still trying to work out repetitive sales timing.

They should have the same caps as the photo but I can't guarantee whether they may differ.  Unfortunately they have ceased to make the original hex caps but there are still odd ones floating around for about $50.00 each
