I called Fairchild Fasteners in Simi Valley, CA to ask about price and
availability of the LiveLock CA 1810 base and the CA 1820-2 stud.  I was
told I would need a retainer for the stud and they sell for $3.50 ea in bags
of 50 minimum order on that part.  There is also an installation tool
required and I didn't bother asking the price on that as I didn't want to
know.
They have stock on CA 1810 at $20 ea.  There is no stock on the CA 1820-2 at
this time.  They are sending one CA 1810 and one CA 1826-1C for me to look
at.
This will be a pricy bit of kit, tho as Brent says it is probably the best.
