If you already have the OE hardware (expensive), seems a shame not to reuse it, but I do not know of polycarb shield replacement for OE hardware (except OE, if they are still available, and expensive if so). Clearview and Cee Bailey both do replacement thick plastic in Lucite, which is plenty safe, and easier to polish out scratches than polycarb.
F4 Customs is great polycarb, but only appears to sell for Interstate (call and ask about tourer).

One may take longer to get than the other so if you are in a hurry, call and ask. Personally, I think any tint other than a very subdued one for direct sun or night headlights is a mistake.
If you want polycarb, and don't mind buying new hardware too, try a National Cycle Switchblade. (Used OE hardware goes for very decent prices, and is usually in demand if in good condition)
