Originally when people did a 6bt swap they used the 4bt adaptor plates a lot of your fredolay and UPS trucks used a 4bt with a th400 trans mounted behind it. The reason you don’t see a lot of guys doing this with the 6bt is that it turns the engine I think 10 deg to the side so the engine is not setting straight up and down witch made for clearance trouble with the 6bt in most trucks. This isn’t a problem if you use a dodge trans. you can use a 4bt cross meber too if you can score one to use with a 6bt.
