Does $450.00 sound reasonable for a 4-spd muncie trans? It is supposed to completely rebuilt. I do not know if it is a m-20 or 21 but it is out of a 68 chevy something. I see this guy at all the big swap meets and he seems to do a good buisness. I see Classic industries sells them for about 1,000. I dont want to buy the cheap one and find out I bought a piece of junk but 550.00 is alot of money to save.
