FBO(not fabo) does sell some good stuff. However most of us just mention to shorten the slots in your stock distributor because once you have the mechanical advance slots shortened you basically leave it and never play with it after that. For this reason investing in an adjustable one is overkill. I would just take your spare distributor, take it apart and have someone spend literally 2 seconds with the mig welder and shorten weld the slots up a bit. Then you can open them back up with a file, dremel, die grinder, etc.
