These solenoids require a mounting manifold.
This is probably why the lot has been sitting there for the last half a year or so without anyone buying it
Ahh thank you sir! Well so far my luck is pretty bad on finding a good deal from a trusted source on a used solenoid anyway.
May have to go new, or maybe I'll try the for sale section here and see what I can find. Might turn out that someone on the forums has a few solenoids laying around that they wanna sell off hehe.
Thanks again for the clarification! I'll keep looking!
