what holds the air compressor lines in place on the rear of air compressor on a 1977 Cadillac Devil

should there be a bracket and bolt?
I picked up a used compressor to replace the one missing from my Cadillac , but do not see how the lines connect to rear of compressor?

thank you

Well i have personally gone through this kind of issue but generally i would say that having ideas through such things always takes care of things for us.
If you get to have about it through some technical sources it can help things to grow for sure.
