mmmm ... all I can say is that I'm 100% sure that the genuine side steps are now OK to fit to the side curtain airbagged T's.
I didn't notice whether the side steps were listed on the TS price plaque at the SMS but they were fitted to the car and when you think about it, Ford could leave themselves open to accusations of misleading people (and also just making a whopper mistake) if they fitted the steps to a car you weren't allowed to fit them to. They could have fitted them to the TX on display if that was still an issue.
As I mentioned previously, I checked with my Dealer the other day when this thread came up and he said he had been officially notified by Ford, just that week, that it was now OK to fit the side steps to curtain airbagged cars ....
If you spoke to a salesman on the Ford stand about the steps it doesn't surprise us does it that he/she may not be quite up to speed, does it? ... no disrespect to them, but i'd think everyone on this forum knows more about the product than the sales guys ... LOL
