Well I went ahead and pulled the frame out of the tub. Just my luck the trans has had gear oil in for 10+ years, go figure. Where do I get parts for the t-20? Does the company still exist? If they do I'm only about an hour from Jonesboro so I could go there. I almost have everything to put it back together all thats left are the axle bearings some clean up and paint and now the trans.
