On the 3600 the shoes are narrower and the wheel cylinders aren't interchangeable with the 3800. I've tried, they are a smaller diameter so the adjusters wouldn't fit. However the springs and such may be. It wouldn't be a huge investment to order it up and try. I got wheel cylinders from Jim Carter on the condition that I could return them if they didn't fit. They didn't and I returned them no sweat. Last I looked he had 1-ton wheel cylinders in his catalog.

As for the fluid leakage it has to be going somewhere. If you have a hydrovac it could be getting sucked into the engine otherwise it's going on the ground or into a brake drum somewhere. Hydrovacs were an RPO on 1-tons. The fluid also could be displacing air that didn't get purged from the system when you bled the brakes.
