[R-390] need R-390/URR ant. trimmer

Hi folks,
	I've been agonizing my way (is that good English?) thru an R-390 that 
I've had 8-9 yrs, and was in rough storage long before that.  Probably 
well used before that even.
	The ant trimmer cap is out of alignment, the rotating plates hit the 
stator plates.  They're parallel, but the shaft is too far to the rear, 
as if it has worn the rear bushing in the ceramic plate.  Bending is not 
a possible solution.
	Does anyone have one of these available for cash, trade, etc.?  It's 2 
section, 6-26 & 7-80 mmf.  It's slightly possible it's like the R-390A 
one, which is mounted in a different area, the values are almost 
identical.  I don't have a 390A at the moment to compare.
	I can try melting out the post mounting solder and repositioning 
things, it might work.  I've done similarly in the far past to an R-388 
xtal phasing cap, much smaller, single section.
	Any help will be greatly appreciated.
73,
