I want to use tow dolly for towing my S13 hatchback. And according to Demco tow dolly instruction, front wheels should be on the tow dolly and rear wheels should be on the ground for good weight distribution. So for manual RWD, the transmission should be shifted to neutral and the drive shaft should be disconnected to prevent overheating the transmission. After disconnecting the drive shaft, a transmission plug is needed for preventing transmission oil leaking.
So where can I buy a 240SX transmission plug? I googled, but no answer.
Please help.
Thanks!

This instruction is only for an automatic of course, manual transmissions can be towed without any damage, just put in in neutral.
If it is an automatic, it's easier to unbolt the driveshaft at the differential, then tie the end of the shaft up somewhere. That way the diff can turn freely but the transmission won't, nor will it leak from the shaft being removed.

I googled about towing manual RWD with just shifting to neutral and no disconnecting drive shaft, but there is no definite answer. Some said no need for disconnecting drive shaft for manual RWD and some said yes. I will be towing my 240SX for about 300 miles one trip from my home to race track once a month. Do you think I should be fine with no disconnection with drive shaft?

A manual transmission (most anyway, the 240SX for sure) doesn't have a fluid pump within it. The fluid just sits in the bottom of the case, pooled up, and allows the gear set to dip through it as it turns. There's no working parts to lubricate additionally while it's in neutral. An automatic on the other hand has a pump that's driven by the engine, not driving it keeps the fluid in the pan, starving the solenoids, bands, and clutches. Some manual transmissions, like say a Ford F350, do have both a pump and cooler, these must be disconnected first as the fluid will overheat. They're designed to run with fluid being pumped up and across the gears.
In your case, depending on how it's towed, some of the fluid will pool in the back of the case, but not all. There's still fluid in it, and it's not engaged in a gear. You'll be fine. But it's not any more work to just pull the rear of the shaft off the diff and leave it loose if you're really concerned.
