The pen bushings and tube charts and apps are close to being finalized. Some new suppliers and the original suppliers also. About 25 total. I'd like to think these will be available by year end 2020.
I do have another 15 or so suppliers that I'm currently trying to compile data for. Many of the new ones are from UK, Germany, Australia, France, Canada, Belgium, China, USA.
These are more difficult to get data from. Not many suppliers are helpful with my requests.
If anyone has data for other suppliers, I'd greatly appreciate the help. Kit names, tubing and bushing numbers, dimensions of tubes and bushings, and instruction files.
