I got the frame plugs made by a guy called Ron Ridley, he has various designs to choose from and they are all hand made, the only plugs he does not make are the large oval ones ( I got mine from Casoli ) If your frame is the round bottom hole he can make one to fit.
I think mine were about £50 and the casoli ones the same.

rocket-ron@ntlworld.com I got my footrests done at a place in Northumberland called Premier plating, Website
http://www.premierplating.co.uk/home.html Any platers that do anodizing can do it, I dismantled the parts myself and you MUST remove the brass bushes from the levers or the acid will disolve them,they are easy to remove, it only took them 2 days for the job.
