Yashica TLR parts

This is a total long shot, but does anyone happen to have a donor Yashica TLR sitting around? I have one with insides that look like this.

I believe it is a EM, though someone cannibalized the nameplate/meter(?) before it was given to me.

Alternatively, are there any good places to pick up parts besides donor cameras?

try the yashica guy..... www.yashica-guy.com or a permutation like that. don't know about a donation but it sure would be worth a try if no other avenue presents itself...good luck. I've been a yashica dude for more than 40 years myself! cheers, sam
