i just put in my original 71 trans back in me z had a 72 trans before went to put the driveshaft back in it is to long measure 27in i had two and sold one which i think was the right size so anyone want to give me the right size this one is 1.5 tolong

 

Sounds like you kept a driveshaft from the early 71's, that had the diff mounted forward.  Might be more that, than the transmission you're using.

Regardless, you should show where you're measuring from.  The whole thing or the ends of the shaft, or the u-joint centers.  I think that there are only two propeller shafts for the 240Z's, the early one with the forward diff, and the later one with the diff moved back.

i have a 71 tran and a72 trans so your saying the trans might be messed up where the drive shaft go in  i am trying to understand what you are saying

I have not heard of the two transmissions being of different length.  Have you measured them to be sure that they are of different lengths? 

I'm saying that I thought that the transmissions were of the same length, so changing transmission should not be a problem.  Only one part number is shown for the 240Z's up until they changed propeller shafts because of the differential placement.
