prc 77 internals needed

I am missing the A40 module in my PRC 77 and was wondering if anybody knows a good source on them. I have been going though a lot of diff suppliers and so far only one has one for $60. Seems a bit steep for one little part for a radio. I know that this is the module that they normally take out to demil them, so they will be scarce, but has anybody got a really good source on parts and accessories for the PRC 77s? Thanks.

It's going to be like the frequency standard module for the GRC-106, rare to none. better get it for that price while you can, it makes the difference between a parts radio worth $100 and a working radio worth $300. Just keep calling around, maybe one will turn up or maybe you can buy a broken radio with that module good in it.
