I've got a Gen-1 TRD (Magnuson) supercharger from a 98 4-Runner. The unit was pulled from the vehicle because the owner was giving it to his nephew and didn't want him having a 'souped up' engine. !?!?!? Anyway it ended up being my project and I got to keep the parts. it's got 100k on it, ran great when it was pulled. I made the mistake of pulling the nose cone back to look at the gears and the stinky oil came out of it. But I called Magnuson and they sell an 'oil change kit' for it. I'll never use it, and thought someone might be able to. I have all of the mounting hardware brackets, belt etc. Make me an offer, I'd love to get it off of my shelf. I'd trade for some FJ40/350 swap parts. Let me know if you want pictures.
