So I tore the rear drawbar guide plate off the back of my 641 and broke all of the bolts off in the rear casting. One of the ears broke off a long time ago. I have tried drilling them out with cobalt m42 drills and broke off a bit in one of the bolts and the other holes are in pretty bade shape also. All that hardware was hardened and fighting all the way. At this point I'm reading to yank the rear and replace it. I live in pilot mountain nc and was wondering if anyone in the surrounding area would have something that would work. I'm not against using an 801 rear end but I'm not sure what the spline count is on my 59 641. My horns and gears are all ok.
