flywheel ring gear question
Ok, so Ive got a motor in my basement right now and the flywheel on it has a bit of damage to the outter edge of the ring gear.
My question is, since they are just pressed on, can I pop it off and turn it around and use the other edge since its still good?
It looks like the gear is directional since the teeth angle one way slightly, but It doesnt look like it would really matter since its so minor (definately better than the crunched up other edge).
If I can re-use it with the clean inside edge, does anyone have any tips for getting the ring gear back on once its popped off? I was thinking that maybe if I froze the flywheel, and heated the ring gear in the oven that it might just pop back on there!, or is there a special trick?
Also, If my theory wont work, is there a place to get a new ring gear cheap?

Man I thought you knew everything. LOL I couldn t find them new either.

then I wouldn't have time for all of you mere mortals. 
So I think I'll remain ignorant in a few areas and can stick around, it's too much fun here to leave anyway.

Actually, having just installed a new ring gear on an '85 12A flywheel, I can tell you that they are tapered slightly inside. Therefore, no you cannot just turn it around.
10 minutes in the oven at 450F, and it fell into place unassisted.
Mazdatrix is the only place I can remember seeing the ring gear listed seperately.
