Agreed. I'd like to keep it original. I was poking around today and it seems to be a 1/8th size in a british standard tapered thread (BSPT), for anyone who encounters the same problem I am having. To be more clear, this is for the block plug that is infront of the oil filter, right by the engine mount on a '70 240z.

On my car, there's a redundant oil gauge. This gauge uses actual oil to detect pressure, and I'm looking to remove this. However, once removed, I'll need an engine block plug, or oil sending unit plug. Does anyone happen to know the proper threading and length for the plug? I do not want to take any risks here, and certainly dont want to mess up the threads and send alloy bits into the block!! Any help appreciated!

EDIT - nevermind. Too much crazy. Reversed the + and - cables (despite labelling them correctly in the image!) all is well!

Can anyone confirm that I've actually got the right wiring? I just connected my battery terminals and I had to disconnect within a second due to the smoke! a ground cable got hot enough that the insulation melted off. Quite alarming.

Top notch info! Thanks a bunch, guys Thanks for the swift response also!! Much appreciated.

Hi everyone, I just took out my transmission and re-installed another one. But since doing so, I've fogotten where the wires go! I want to be extra safe so as to not short anything out. Can anyone identify which wires go to the starter, and which go to the transmission? Pictures will help big time! I am assuming the negative battery cable hooks directly to the starter... but the remainder I'm not so sure! EDIT: this is on an early build 240z

EDIT - The motor bellhousing does bolt up. However, if you're dealing with a type B 4 speed in a car that was built for type A, then don't learn it the hard way as I did: 1) The type B transmission seems to the shorter--it moves the shifter approx 1.5 inches further forward. This necessitates what looks like a required additional cutting for the shifter in the center console (that hole!), and likely needs a whole new center console to accommodate.

Greetings! I have a '70 240 and have a 5 speed bolted to it. Unfortunately, my 5 speed blew, and I'm putting in a 4 speed in temporarily. I've removed the old 5, and slid the input shaft of the "new" 4 speed into the car. Oddly, it appears that most, if not all bolts on the bell housing do not line up with the engine block!! Is this normal? My motor is an L24. The 4 speed is from a '72 240. I figured that a 4 speed out of a later model 240 should bolt right up into my early model 240 (since they both came with the same motor). Is this incorrect? It even appears that the dust shield on my car doesnt mate up to the transmission... Any help is much appreciated. I'd really like to get this thing back on the road:stupid:
