Need corrosion resistant sliding glass door wheels

Dear Sir:

(1)
I am looking for sliding glass door rollers. I contacted you a few months ago, and have finally gotten around to getting photos and measurements of the roller assemblies I need. See attached 7 photos that should contain all the info you need to determine what I need. Note that these roller assemblies are entirely made out of metal.

(2)
I need sixteen (16) of these roller assemblies.

(3)
Can you provide me the price of these wheels in both stainless steel and non stainless steel ?

Sincerely,

Randy
