Installing inflation valves on DUI trilam suit

[Dock]

I just purchase two "army" model trilam DUI siuts from a friend. These suits come with exaust valves but no inflators, otherwise they are the standard self donning suits.

Does anyone here know the cheapest way to get valves for the suit?

How about the process of instalatation of the 9inflator valve?

Any info or ideas would be helpful.
