I have an imco tank, not sure if the outlet is 1", I think it is. Ill have to check tomorrow, don't have the mounts. It's 5 gallon polished aluminum . I believe we spoke before about it, but I wasn't sure if I was going to need it.
I have an Olson mailbox scoop for sideways dominators. Ithink c-c is 8 3/4 ". I will have to doublecheck that as well.
