My 96 f150 died back in december and I had to buy another truck, but I still have the 96...just couldn't part with it. It's a great truck. 4x4, 5 speed manual (mazda), fairly new clutch and slave cylinder...the engine is just trashed. I was toying around with the idea of getting an old 7.3 IDI diesel and putting it under the hood. I don't know if I will be able to use the clutch and existing trans. I know, from the little I've read about switching from gas to diesel, that I'd need a bunch more parts than just the engine to make the swap work, but I was wondering just how hard would it be. I'd be doing all the work myself so my only expense would be parts and maybe a few new specialty tools. Anyone who's done this swap, I especially want to hear from you. Thanks.
