More of a concern is the shutter speed indicator strip. It's attached to a string. Could be easily damaged, if you're not careful. Also, have a soldering iron handy, since you may want to disconnect the sync terminals to get the top cover completely out of the way while working on it.

That said, just keep your eyes peeled on the KEH outlet eBay store. Next time a lot of Nikkormats comes up for auction, bid on it. You're likely to find a nice FTn or FT2 that works fine, but that they decided wasn't worth selling with a warranty.
