I will not part with any of my sources. 77 has them on there site I think. Sorry I am not coming off as a dick. Just I have researched endless hours and translated a shit of website.
So I would search researching. If I get them.. I will post one on ebay at .99 and we'll see what the fare markey valve is on them. Many Thanks. Ed
I don't know anyone that would just give up where there parts come from...
