Just received my first camera and want to replace a few parts that are showing wear and remove the foam while I’m inside. Can someone point in the right direction besides eBay for replacement parts? I know this is an old old camera so parts may be limited or should I roll the dice on a parts body?

Edit: please recommend any parts that can just be upgraded as well. Currently have a microprism but should I even replace the screen for a split?
