What does it cost?

I'm on my second 68 fastback and will do all the work to it. I have a spare running engine and 727 to install. I just need an 8 3/4. Even doing ALL the work I will have more in the car than it's worth. It will be close, but still will cost more. I don't have the $ to buy one or pay someone to do it, so that leaves me. Keeps me off the couch!
