I have a 69 cj6 and want to put a 4 speed in it. Does anyone have any suggestions for a strong unit that will bolt to a 225 buick v6. I want something that wont clean out my wallet so I would kind of like it to bolt on without an adapter. I know that some came with a 4 speed but ive heard that they are weak and rare. Any help on the matter would be apreciated.
