my cruiser has jul 1985 on the plate inside the door jam, also it looks like I have 2 and a f with a circle stamped on my original tranny, So I guess I have a 2F tranny, it was stamped on the drivers side of the tranny. So if I wanted to do the conversion to the h55f, mine won't just be a simple bolt up? I will have to do other mods to make this conversion work? Is this true? what all should I start getting together to do this and what should I expect to run into as far as mods go? all the help will be greatly appreciated Ps. I have read some things through the search function, but not all. My work has me bogged down right now and I'm not able to find as much computer time as i need to get all the info.
