I found one on eBay... expect to pay at least $50. I found a brand new one locally for $237.
The 80/81 are different from the 82/83. From a visual inspection they appear to be the same assembly housing, yet the piston and other parts are different. I believe you may be able to get a rebuild kit and replace the differentparts if you can't find an 80 or 81. Another option is touse your old parts on an 82/83 assemblyif they are still good.
