Fasteners at John Deere.

Back many years ago, my brother worked at an International Implement dealer. The front main bearing, the 307 was going bad in his 69 Dart Swinger 4 speed. He found a bearing on the shelf that had more bigger balls with the correct snap ring groove. Then a couple years later, I needed one for my 68 GTS 4 speed, which I still have. If I ever pull the gearbox apart I will get the bearing number and post it on here.
