That's a fair quote, about the same I charge. It's an ugly job even for those of us that do it all the time. Not my favorite to do in the car. A proper engine holder really makes it a lot easier. Although I am sure there are those that have used a 4X4 or big pipe and chain. Not really a job I would recommend for someone that doesn't have some backup and a lot of patience. Arie and the crew will treat you right if you go with them. Last I heard Dealerships in Tucson won’t take in any older rotary, pre 8, anymore.
If you do the front cover as long as you keep the keyway from coming out with the damper you shouldn't have a problem with the thrust bearing. If the trust sleeve is kept place the bearing shouldn't move. During assembly once lined up I pull the eccentric shaft forward to keep pressure on the bearing, done a few motors so it is second hand. Vaseline won't hurt.
It is critical it and is easy to get wrong. Don’t know how many home builds I have taken apart that had crushed bearings, even had a mana with one. Most all of these were before there were any forums though so there wasn’t as much help for DIYers. Factory school was about the only way to get any of the tricks back then. Instructor would point out, BTW you won’t find this in the factory shop manual. I’ll admit it I’ve crushed one, got distracted. At least I knew what was wrong when I checked end play before putting front cover on.
Since the UV showed what it did and that is a common failure point it probably is the gasket. My experience has been that the hoses are pretty obvious when they leak. As you have easy access now easy enough to see if there is any oil in them any way.
