I called Ruger today, as nobody is stocking them. $7.00 each from Ruger, p/n MVQ 10800 for blued. I ordered them for my .44 spc Blackhawks. If you want stainless, check the Ruger website for the part number.
I fitted one of the New Vaquero crescent ejector rods on my Bisley flattop .44 spc, and there is a bit of a gap between the barrel and the top of the crescent. I think it is more so than on the New Vaquero (didn't dig it out to compare, but looks about the same as on Gunblast http://gunblast.com/Ruger-NewVaquero.htm ). It is sharp, and for $7.00, I smile.
I did fit aftermarket ones on a Blackhawk and Vaquero. One required some fitting, the other was used with and aftermarket "cammed" ejector rod housing, and required no fitting.
G2,
Oooops. How about $38+. Sorry. I had to do a little bit of filing on it to get it to go into the steel ejector rod housing but if I can do it with my 10 thumbs then anyone can. The gun its going on should be here late next week. I don't see a problem.

I've tried a bunch of them and Clements' (center) is the best of the crescents. Although my favorite is the bullseye but it also takes a good bit of fitting to make it operate smoothly.
