The ultimate solution is to do what I did and replace the entire front end from the sliders down. I did this on my 83 with parts from an 86. I also upgraded the lines to stainless braid and while I was at it I powder coated the front fork lowers and upgraded the suspension to progressive springs and gold valve cartridge emulators. The stopping and handling on the bike is (for a lack of a better term) "reborn"! If you really love the bike to start with I recommend it!
Many folks right here on this site "held my hand" so to speak as I did the work and I know they will step up again to help you!
GO FOR IT! A new Venture experience awaits.
