Trying to get Drive shaft to fit!~!!!!!

Kk so I got a 240sx and had to put a new Eng and Trany in it. It was a AT but I am changing it to a MT. I went from a KA24E or what ever SOHC to KA24DE DOHC. My Drive shaft is too short And I cant get it to fit. I got a drive shaft off a MT so I have no Idea what the problem is/ Plz some one tell me what the hell is up

is the mt drive shaft from an s13? if it is a s13 abs shaft that might be the problem. I can’t remeber if there the same lenght as a non abs.

ABS and non-ABS s13’s have different size driveshafts.

hahahahahaha some fucking problem im having its its been going on for 2 months ya the abs and non abs are different sizes thats your problem
