I may not be in the right place, but here goes. I recently bought a '71 510 wagon, i have fell in love with it. I am wondering about the options for a tranny replacement, it is now a 4 speed on the floor, how can I make this a 5 speed?

So,... you have "fallen" in love with your 510 wagon, well that can only be a good thing. The five speed tranny from the series one & two Bluebird is a good choice & they are overdrive types. Another is the dogleg five speed from the 200B SSS, & these are also overdrive trannys, but a bit hard to find & they really offer no real advantage over the Bluebird one.
All of these trannys were originally fitted to L series engines & may even fit right up into your chassis with a bit of luck.

First question is where are you located?

That makes all the difference in the world.

yeah where are you? the 240k 5 speed is also good. quite strong too, as they originally came behind a 6cy L series. and i know a pick a part style wreckers that has one in melbourne......

the shorter boxes would be the better option (same length as the 510's 4spd), but as tens_and_twenties said, it depends on where in the world he is... I assume he's in the USA because he referred to it as a 510.

Yeah, in the US your best bet is to find a short tail (short box) 5spd from a 77-79 200Sx. It is a straight bolt-in for a 510

i am in the unites states,thanks for all of your input
