Sorry for bringing this page back from the dead but are you still selling these?All,
I recently had a copy of the always broken press-in drain elbows made for a restoration Im doing for a friend. My local job-shop machinist made them out of brass. We made a few extras for now, and I will sell them to anyone who needs a pair. Im using them on the SOLEX carb bowls with the 1/8th in. pressfit hole.
They are made here in the USA, and are "pre-production", meaning that the ends are correctly sized but some of the bodies may be taller or shorter than each other a bit as we have not dialed in the optimal lengths and widths of the parts yet. I will bag up pairs and sell them for $35 if anyone wants them, and will update when we have more, standardized runs made. If there is sufficient interest.
