Vintage Synth Repair

Hey all.

I just purchased a 1977 model Moog Micromoog in awesome condition and 
playability except for two small issues: The pitch ribbon no longer 
responds (would seem typical) and the first octave E note seems to 
have a bad key contact because it lays fine when you kinda slam down 
on the key but I noticed this problem after I opened up the synth to 
clean all the ivories.  Coming from what I've seen, it's a very basic 
synth inside and a lot of air space.  My question is, how easy is it 
to replace the pitch ribbon material?  Kevin from Synthfool has the 
material for sale but he asked me if I was sure I could manage the 
repair myself so now I'm a little concerned that it will be more 
daunting than expected.  Any ideas?  I do have a service manual... but 
it doesn't help for logistics.  LEt me know if anyone has experiencde 
with this.  Thanks!

Mike
