240SX Flywheels, 89-91 same?

Hello all, I have a 91 240 and the boolts that hold the fly wheel are stripped and some brocken in the crank, there is right now a 240 in the junk yard, but are the flywheels the same, the one in the junk yard has no head on it and a lot of the engine bay is gone, the engine code is KA24 but mine is a KA24DE is there a lot of difference in the two?
