[R-390] Help needed for two R-392s

I purchased three R-392 receivers at auction.  My plan was to restore 
them and get them working and then sell them to help pay for the one or 
two receivers that I want to keep. I ran into a significant roadblock 
when I opened the first R-392 and noticed that all three slugs from the 
2-3 MHz variable IF were missing.  I opened the second unit and was 
horrified to find that the entire 2-3 MHz IF tuning rack was missing 
along with the slugs. The third unit did have the 2-3 MHz parts and I 
fired it up and have it running pretty well. The PTO is off by 4.2 kHz 
which isn't too bad. There are some dirty switches but it looks like I 
can get unit #3 working again.

I looked around on E Bay and see no modules or components from the R-392 
for sale. I am hoping I can find some parts to get at least one of these 
receivers working.  So my question is Does anyone have any R-392 parts 
units that they would be willing to remove the 2-3 MHz rack and slugs? 
What really bugs me is that the unit that is missing the three slugs 
looks pristine inside. It is gorgeous!  Needed are two sets of slugs, 
one 3-2 MHz rack and the two springs that guide the rack on the cams.

I hope someone can help. I enclosed a picture of the 2nd variable IF 
slug rack and its location in the upper left.
