$66.00 certainly seems a lot for a simple job like that (including supply frame and rivets, of course). I charge only £12.50, inc. postage (usually about £2.20), here in UK, but trans-Atlantic shipping would almost certainly make this an uneconomic proposition for someone in US, I'm afraid.

At least I now know how much it'd cost 'nearer to home', for a US repair. I think Brooks charge $98.00 (inc. shipping).
