I was able to assemble and turn the compressor on last night, awaiting the oil (thanks, Knife) before running it.I found screws in my parts bin that were for a TV mount I got a dozen years back, I will braze a washer to them for now then will make/buy a couple knobs if I can identify the threads. I have a thread guide, just too lazy to dig it out!
