Assist/advice questions

Aug 18, 2005
As I am in the process of rebuilding my other Norton- the winter project is on and the wife is mad as sh%#t cuz there's parts all over the basement floor-I am running into a little problems and could use some advice.So here goes.
1)where could I a new set of rings for the Dunstall 810 kit- I broke a couple while trying to take them out
2)do they sell only the screen for the petcocks and how would they be secured to the petcock
thanx in advance
