Check Ebay. Usually overpriced but there are many and priced between $1000 and $5000, generally in the mid teens. Mostly new or rebuilt. I think T5s have replaced the 4 speed market.
For what it's worth I had a mid seventies M20 Muncie that worked fine (I drove the car it was in for a few days) I had it for sale for six months with little interest and finally sold it for $650.00
Thanks for the replies. I figured as much. Ive seen them for like you guys said 1500 or so but they never seen to sell. The $650 you sold yours for seems more reasonable.
Im not restoring the car back to stock, and the M20 wouldnt handle a twin turbo ls anyways. I need body steel more than the trans now anyways.
