Searching for OP05-2047

I am looking for stainless steel replacement parts for several American Craftsman double-glazed awning windows purchased from Home Depot in 2007.

My windows:
-two sets of full window awnings 7450 7452 A-2H double horizontal awning 4828
-one set of full window awnings 7450 7453 A-3H triple horizontal awning 8517

There is a serial/model# (?) engraved on the upper hinge of all windows: HG04 2004U
Number on the drive operator of the triple awning cranks: 3113
Number on the drive operator 3236 (upper arm) and 3027 070605 (lower arm)

FYI, I purchased two replacement stainless crank-outs in 2010 for a set of twin awnings, engraved with #0P05-2047, which I recall purchasing directly from American Craftsman (but am not sure); more of these would work well, but today American Craftsman informed me they only supply parts for warranties.

My aplogies - I cut and pasted from another document and realize I left out some basic info from my first request.

I have 7 American Craftsman awning windows in need of various parts. American Craftsman will replace all items under warranty, however I prefer to upgrade to stainless operators and hinges, which they apparently no longer have. I replaced two of the original operators in 2010 with stainless, engraved with #OP05-2047.

So, I need:
- 5 new stainless steel drive operators
- hinge arm assemblies (left and right) for one of the larger awning windows.

I hope the photos speak a thousand words.

Thanks! Lisa
