Rear Engine Plate Difference.

I'm finally removing the automatic transmission out of my 71 240Z and installing a 5 speed thats out of a 78 280Z. After checking out as many threads on this subject, it seems that the "rear engine plate" is different for either transmission. So whats the difference between the two? Just curious.

My understanding is that the main difference, and maybe the only one, is that the bottom portion of the automatic plate is removable so that the torque converter bolts can be installed and torqued.  The plate is actually just a dust and water shield so that makes sense.

Automatic engine plates are a two piece affair. It allows the mating of the torque converter to the flex plate after the transmission is mounted.

 

Parts manual shows two plate numbers L24 through the L28. 30411-E3000 til 7/73 and 30411-R8600 after. Images of both versions show the triangular opening.

 

I have no idea where the round hole version came from.

Do you have your swap parts all gathered? I can help with that if you need goodies. Clutch pedal? engine plate? hydraulic line? Let us know what you need.

Don't forget the knock the spacer off the end of the crank and to put a pilot bushing in the guide hole in the end of the crank.

Also I would think you would want to add the hose mount to the frame of the car. I had to add it on my car. It holds the connection from the hard line to the flex hose on the frame side of the car, below the battery on the inside of the frame rail.
