I'm thinking about buying a 87 535 any I found one that is in really good shape for what the guy wants for it, the bad thing about it is that its an automatic and I was wanting to know how much a trans. swap would cost me.

Are you doing the swap yourself or would you be having a shop do it?

I am actually doing one myself. I have a doner car, what is a good estimate as far as price and time? Are there any DIY articles out there?

It's not terribly difficult but it is labor intensive, especially if you don't have a lift. This site should set you in the right direction.
