Vintage Synth Repair

Hi everybody!

Yesterday I finally got me a Roland SH-101. Nice little beast I think ;-)

Unfortunately the pitch bender is broken and needs replacement.
Has anybody in here ever tried to replace it? Is it difficult?

I've found a replacement kit on Ebay. It is a clear bender with blue light. Not from Roland 
but a re-produced one. Though I would prefer an genuine Roland pitch bender, I realize it 
is difficult to find one, and probably I will have to buy the clear one.

Also the gray cabinet on my little synth is no longer gray because of smoke. Anybody with 
experience in cleaning it?

Any help will be appriciated :-)

Cheers
