Model 45 motor grader-Master Cylender-looking for parts rig

I need a few things fixed on my grader before I decide to sell it or not. (This is not the WD45 small grader.) First of all I need a re-build kit for a "Wico Powermaster" master cylinder. I assume this was also used on other equipment or tractors but I'm not sure. I'm hoping someone here will be familiar with the larger Allis equipment and may be know where I can order a re-build kit before I start wasting phone calls. (My local Agco dealer isn't much help with the old stuff and I'm in a pretty rural area.)

I'm also having a problem with what I think is in the gearbox that turns the blade "circle". This unit is hydraulic/mechanical meaning that a hydraulic pump drives a mechanical shaft that enters a gearbox to turn the circle. Something appears to be sticking or possibly slipping inside the gearbox then the hydraulic lever inside the cab locks up. I'll be taking the gearbox apart when I can get to it but it appears that the former owners had this problem before as it is sealed with RTV. Anyone familiar with this problem? And might this gearbox be the same as used on the Model "D" or "DD"?

As with most old tractor parts it is often easier and cheaper to find a "dead one" and cannibalize it for parts. Anyone know where there might be a Model 45 sitting/rusting away? I could also use a good manifold for a 516 diesel before I attempt to fix the crack in the one I have. Need 4 good tires too.

Sorry for such a long post but while on the subject why not cover it all? There were a number of attachments available for this unit including a snow plow and bulldozer blade. I know I'm reaching but might anyone know where such things might be lying around?

if you dont get any help here, you might try www.ibdozing.com those guys talk about construction equipment. I have seen a 45 grader, and one was sole on e-bay about 6 months ago. The guy had a post on this board about the desiel engine.
