Ok, looking into a diesel, wanting to purchase an older one, but my knowledge in this area is limited to CUCV's & HMMV's mostly.
So what I am looking to find out, is what is the difference between a mechanical diesel, and a newer model diesel.
Also, which one is better?
Are there diesels out there that dont use any type of electronics?
Is there a better make/model/manufacturer that stands out?
Im assuming, that if I purchase a older vehicle to convert to diesel, its basically a engine swap correct?
Is there anything else I need to know?

The basic idea is Im wanting to purchase a Suburban style vehicle, add lift kit, push bumper, ect, and put a diesel engine in it. BUT the parameters are, I dont want any type of electronics in it at all. So, who has suggestions, comments?
