Very nice.  One of my favorite airplanes.  Thanks for sharing the photos.

[Aircraft Maintenance Questions (Vietnam)]

Hey MM.  A basic Air Force turbine airstart cart is the A/M32A-60, which was used in Viet Nam and a variation is still in use today.  In the navy we call called them "huffers".  For flight deck use,  huffers were usually found attached to the back end of a standard MD-3 shipboard tow tractor.  We also had huffers similar to the Air Force units that were towed and not attached to a tractor.

I can't address F-105s, but, in the Navy, we used a variation of a bottle jack to change tires on F-14s and F-4s. 

I've attached a picture I pulled from the web of an A/M32A-60 start cart and an F-4 in Viet Nam.

Hope this gives you something to work with.
