I just got my Mustang Daytripper in today and tried for an hour to make it fit. I do not think it is posible to get it on. It goes right down on my ECM bolts and stops. Anyone else have this problem on and 06 FXST (B)
I even verified the part number with the Mustang website and it shows it should fit.

 

Greetings,

I ran one of those on my 05 FXSTB and it fit without issue. It's possible the wrong seat ended up in the box that had the correct part number. I would call Mustang and ask.

 

I have the same seat on my 07 Train. Fit is perfect. On the underside, there is a indent for the ECU. Check to see if your seat has that.
