I had try to let sleeved my mc,but the machining shops told me, it isn't possible at this part.They can overbored it and build a new Piston for it.
That wasn't ok for me.
The Remanufactured mc ,I heard not so good thinks about it...
After search arround i found the Mc 2796 from a CJ 6 Jeep, it match nearly perfect into the car,had only to build a mounting adapterplate and need a fitting for the line (thread is the same,but another sealing style,inverted flare 1/2"-20,Edelmann # 265500 ) .
Inner dia of the Cylinder is also 1".
