Eli,
I'm looking for a turbo on a wreck/junked truck & in about 10 States, as I write these lines. - I cannot afford a new set-up on my pension. = The parts alone are 1500.oo.
(There's a whole herd of IDI fans in the USA & we all help each other. = For example, a fellow who I met on one of the forums has found me a FACTORY Ford diesel manual.)
yours, satx

Ask on OilBurners if it'll fit, I was somewhat on there when I actually did stuff with my '90 model aside from very basic maintenance.
