One option would be to buy a rebuilt 280 distributor and return your 240 distributor as a core. It would cost you about $125, and the unit would be fresh.

do you know where i could find one?

i looked it up but im not sure if its electronic

I bought a rebuilt one from AutoZone -- lifetime warranty. I've heard some of the rebuilds end up with a bent shaft, but mine was fine. I like the lifetime warranty because this wasn't exactly Datsun's best designed part, and it's prone to failure. It's easy to R&R, so a part with a lifetime warranty is a no-brainer. Here:

A Pertronix distributor (which has its own ignition module) would be another obvious choice -- perhaps a better one, as you'd otherwise need to put together the rest of the electronic ignition. That said, I retrofitted my 280 with a GM HEI ignition module. There are plenty of threads around that will tell you how to wire one. The retrofit cost me $14.
