So, continuing with the RX-7 engine rebuild, I have come to the flywheel. After cleaning it up, it seems to be in pretty good shape. No broken teeth or other damage. If I rub my fingers over the friction surface, I can feel very slight undulations, so I'm guessing a resurface might be a good thing? Can any good shop do this?
I probably wouldn't bother if I was putting the old clutch back on, but a new clutch is here and standing by for installation, so I want to do it right.
Pic of flywheel:

My local transmission shop does them for me while I wait. They keep track of the amount of material they remove and include a flywheel shim to compensate.

Not expensive at all.

Nice!
In reply to 1988RedT2 :
If you can, find someone to resurface it. The new clutch will grab better with the new surface.
Done!
Sadly, unlike some people, I did not have pictures of the shop proprietor in bed with another man's wife, so I paid $60.

80 bucks here, Never heard of the shim before but I can see the argument for it.
I would not do a clutch job without because of the PITA factor if it is not right.
After my last ring gear flip I tried a new way to resurface a flywheel. You see I work right near the machine shop where we have a large surface grinder or two. It worked really well, no pics.
We just sold our Blanchard grinder, the machine that provides the nice swirl pattern, turns out that a clutch doesn't even care.
I've done them on a lathe, had them done on a brake lathe, done properly on a grinder, and also with a flap disc on a 4" angle grinder, and done nothing.
They all worked fine.
I just hit my own with a flap disc or roloc and send it (drag racer), for customers the machine shop up the street charges $50
