You don't need to purchase a new wing just cut the STA out. If your wing has an STA then I am not sure what the advantage of a reverse profile plate is. As far as customer service here is an older thread:
http://www.scubaboard.com/forums/golem-gear/422154-unprofessional.html. Probably the best advice is call to make sure the item is in stock before ordering.
I emailed them 4-5 days ago with a couple simple questions and still haven't heard back. Custom Divers in the UK replied to my email in 3 days.
I really don't want to cut up my wing just to use a reversed profile; they do make a standard profile.

Called Edd (at Cave Adventures for those who don't know) and got a great deal.
I ordered the OxyCheq SS Travel Plate, Dive Rite Basic, 1.5" crotch strap.
The Golem Stream looked great but, I couldn't get correspondence with the company, customers reported sharp edges, the reversed profile may have had an issue with my current wings, and price was higher with all that included.
The Custom Divers was reasonably priced until you had to add the required STA. Had it had cam band slots I would have jumped on it. CD does make a lightweight STA in Aluminum but it's around $65, bringing the package over $200 with shipping to the US.
The OxyCheq wasn't my first choice but they are readily available (Cave Adventures), known quality, great price, US Made, and I know they are 100% compatible with all the other Oxy stuff I own. This option also provided the best overall value.
Thanks again to everyone who tossed in their $.02.
