700R4 GM in a Swinger?

Yeah, if I did it, I would get my own tranny and have it done, then buy the adapter/cables/etc. from them or someone else...they want around $1800 for their 700R4...I know I can get one and have it built for less than that...Craigslist here in central Ohio has several plain 700R4's for $150-$400. As far as keeping it Mopar, I would like to do that but if it means beating my floors in or cutting them up, I'm not going that route. Thanks for the input guys! I love this site....I'm always reading the different posts and seeing what everyone else is doong with their cars!
