THey may think you're crazy because you're asking the wrong question. WHat you want to know is about replacing the old-style valves
with OPD valves
It is not a difficult job per se, though your dealer will want to know the "DT" figure that is stamped into the collar of your cylinders. That number will tell them which OPD valves to order for you.
Since you still have the old valves, I assume that your cylinders are also beyond their certification date. This being the case, you'll want to have the cylinders recertified while in the shop for the new valves. (Visual recertification is often free of charge, but you'll need to fill your cylinders at that place as a courtesy.) For recert, be sure your cylinders are in good condition: No bends (especially along the collars and base), no corrosion, etc.

No one has any idea how to do what I'm talking about. I believe the new regulators are female and my hookup is also female (maybe I got this backwards?) and I need new gauges and recert. It seems to me like it wouldn't be that hard but all I've ever gotten is blank stares and shaking heads.
Thoughts?? I've tried Ferrelgas and Amerigas and some local places. I'm in Santa Cruz CA for reference!
