70s Power Wagon Ignition switch info needed !!

The most common thing I see with those style of ignition switch is they get loose and either barely reach the "crank" position or they don't "spring back" from that position. The spring inside breaks or wears out and no way to fix that except for replacement. You'd certainly destroy the switch further by trying to dismantle it to do something about those issues.
I've bought a couple via eBay brand new but probably 25-30 years old. Much better quality than current new stock and in most cases cheaper. Back then the"standard" brand was pretty good.
