In the end we ordered using the KYB part number. They fitted no problem but are a little "fatter" than the ones that came off. The car is sitting quite a bit higher, but I'm sure it will settle with time. In fact, I actually wouldn't mind a little more ground clearance.
I had that exact issue. Just go onto Autotrader and find a Bravo, then use that registration number! If they still say no, just find a different parts factor.
