[Elecraft] K2 LCD Backlight Diffuser

I am just getting around to building my K2 that I purchased in 2008. 
I've been busy. But I'm having fun now!

I have  the K2 Owner's Manual Revision G, May 29, 2007. I also have 
Errata sheet Rev. G-1, Dec. 12, 2007.

In the Front Panel section, page 27, the original instruction advises to 
use two spacers at each end when installing the LCD backlight diffuser 
to keep the diffuser exactly 1/8" above the PC board. The Errata sheet 
clarifies to use the spacers but remove them after soldering the 
diffuser into place.

The issue is that the two spacers are 1/8" thick. The diffuser leads are 
exactly 1/8" long. This means with the spacers in place, the diffuser 
leads don't actually reach the solder holes. The lead ends are suspended 
just above the holes. If I actually manage to line everything up and use 
rubber bands to hold all in place while I solder (good luck!), the 
solder would need to bridge up to the ends of the diffuser leads for the 
soldered connections to hold. This doesn't seem like a good practice.

Is there a newer errata sheet? Or am I not understanding this correctly?
