I never did look at those under the hood in service...I did crash recovery and flight control systems rigging and landing gear and canopies on f-4s and f-16s. We had a crew cab Dodge pickup and various tugs and our 50 ton crane, a 1959 Ford diesel thing...I should post pics of that...it was unique in my experience.
Pretty much, thats all we played with...pre Hummer days...never even rode in a 6X6...seems odd but thats what happened.
