Rebuilding or finding parts for petcock?

[Bobbity]

1980 B750C. Petcock leaks pretty good when it experiences any vibration or movement. I opened it up and it has the 4 hole rubber that most bikes of the era had. It's 23MM in diameter. I found one on Ebay, but it was a 20MM. Anybody have any bright ideas that don't involve a second mortgage or explosives?

Would something like this work?  Honestly,I didn't realize you could get a universal petcock until i searched for this.I have been riding with a ball valve for my 'petcock' and do not have a reserve. I'm getting one! I guess I owe you a 'Thank You' for that!

Well, if you can't find a rebuild kit, this place has different, but compatible petcocks for $20...it has the line coming out of the side instead of the back...

And this place has a $30 replacement type with a side outlet also, but their outlet is threaded in and they offer a 90 degree fitting replacement too so you can point the line to the back once again....

Or this place has the oem style petcock for $55.96, but they don't have the separate parts to rebuild it...this is the place i got the parts to rebuild the petcock on my 1974, so i'm a bit disappointed they don't have yours too.
