Re: Problems with the engine swap
The original auto trans that would have some with the 200 in the mustang would have been a ford cruise-o-matic. Though it looks like there may have been 2 different types.
I believe you can mount up a c3 and/or c4 will mount up with the right bell housing. I know a couple die hard ford gear heads (my dad and one of his friends) that would know. I will ask tomorrow and get back to you tomorrow.
