Over the summer I have been driving my 48 maple leaf 2 ton a fair bit, when driving loaded the engine will torque over and the fan will rub on fan shroud. After inspection of the rear engine mounts (bellhousing) I determined that they are totally shot. Now for the difficult part, I took the mounts out and cant find anything like them, they are a rectangle about 2.5" long 2" wide and about 1.5" thick with a threaded hole centered in them on top and bottom, has anyone seen this type before? I talked with chevs of the 40's and they had no listing for these, just the 2073 and 2060 that I found locally before. Any insight would be much appreciated.
