These are army service manuals for the 6.2 & 6.5. They are in PDF form. I am having some trouble getting them to upload into my file hosting site but I can e-mail them to anyone would like a copy.

I've got those on my website...

Cool, I just got them from my maintance unit, Thought they could be of some use to anyone else with a military 6.2 or 6.5. Might as well share the info everyone.

Is the EFI 6.5 manual available?

I haven't been able to find one, anywhere.

I have it, whats your e-mail and I will send it to you.
