There have been some who would like to see a repro of the factory kit and one member was thinking about doing it at one time. Haven't heard if anything ever happened though.
Some have used modern remote reservoirs by modifying the existing cap but the kit that is most complete and comes with a new cap is sold by a fellow in Texas. There are some photos of it on Big Kevs blog if you want to search.
The contact info for the person selling that kit is in the fourth post on
this thread The info is almost 3 years old but as far as I know it is still good and the kits are still available.
