Inspection of a 904 torqueflite

If the bushing cocks the slightest bit, it will be amplified by the large diameter of the plate. I have a thicker steel plate for the bottom and it's also a large diameter. Looking between the two plates; it's easy to see if it's starting in straight. First time I needed a bushing it was to install a wider one in a th350. So I bought two bushings and took it over to the local machine shop. I handed the guy the drum and bushing and he said I'll be right back. I said I got an extra bushing if ya need it. He said no. Two minutes later he was back for the second bushing. THAT'S when I decided to learn.
