upgrade from a 4spd to 5spd???

[farmer260]

im upgradeing a lot of my drivetrain on my 73 dart sport and a freind of mine figures i should go all out and put a 5spd std trans in place of my stock 4spd std trans! just out of interest is there a 5spd or even 6spd trans that will bolt up without going to a new trans. in the aftermarket?

there were 4 speed over drive tranys in some of the 75/76 darts,dusters aspen/ volares in slant 6 and 318 cars,, some times you seen them for sale on this site,, or othere sites,,, passion performance makes a new gear set that will install in your case,,they also have a complete trans,,they advertise in most of the mopar magazines,, and mopar is soon going to add this guys trannys to the mopar peformance parts catolog,,, its a direct bolt in,,
