86 4kq instrument cluster HELP

[Shaggs1996 at aol.com]

Ok, Ive mastered these clusters inside and out, but this is one part that 
really makes me mad.  First off, Ive had to remove the original cluster a few 
times to fix the odometer, no biggie.  Not even a month ago, the circuitry around 
where the 2 light bulb holes are at pretty much got destroyed, and wouldnt 
make contact.  I tossed in another cluster, removed it again to replace the 
tachometer, reinstalled it again.  
Now here I am, one of the light sockets wont work due to  half of the 
circuitry being too messed up.  I hate this, Im gonna have to remove it again and 
figure out how to fix it.  
Is the cluster salvageable, light wise, can i fix the circuitry without 
replacing it?  Id love to hear if you guys have any tricks or tips on how to do so, 
Ive about had it with this thing.
Sorry for the rant, and I do appreciate any help.
