trans question

Thanks, what should I expect to pay someone to re-build the trans if they are not really all that complicated assuming I remove it and take it to them?

I guess I also have this option that someone pointed out to me on the slant forum. http://www.makcotransmissionparts.com/A727.html

Any reason you guys would stay clear of this in the box deal?

Since its behind a slant six are the internals different or all 727 the same? Do I need to narrow down the year of the trans and how would I do that if needed?
