Another ac mounts combination problem!

[Speedhorn]

Hi there.
I have searched and searched and come to the conclusion that I don't have what I need to mount my air conditioning compressor on my engine.
The vehicle in question is an 81 c10 ac vehicle, I bought it with an engine as a box of bits , I a now in the process of restauring it completely air ride torq thrusts ect.
I also bought what I think is a military spec k30 85, there is a fair few differences with the engines from what I can work out one of them being the ac pump brackets. I literally have a box of brackets from the 2 engines but no combo seems to work!?
Any help would be really appreciated.
The big problem I have is I'm in spsin so getting spares is extremely difficult.
Thanks in advance
