Hey guys! I told you the 128 resto would begin this winter, but I couldnt wait. So here I go. I tore the old girl apart, not a single problem with any bolt. Got some Q's, I found some red paint in the battery/fender area. I am sure this is original, did IH use the red color as a base coat, havent seen it any where else on the tractor. Next, what is the hole in the top of the differential, offset to the left when standing behind the tractor. My parts donor 149 doesnt have this hole, any ideas?
