Hey guys im new to the forum! Ive been doing a lot of research lately on swapping an ls1 with a t56 transmission into either a 240 or a 280 Datsun. From what I have found this engine/transmission swap is pretty easy compared to other cars. My issue is that I have been unable to find a good website for parts. I have been able to find engine/transmission mounts, but have not been able to find a driveshaft, wiring harness, exhaust piping. Do any of you know of a website that offers these parts, or datsun 240/280 engine swap parts in general? Lastly, are there any other major parts that I will need for this kind of swap? I would like to say thank you in advance!
