08 YZ450 Handlebar riser height?

[nucular]

Could someone tell me what the OEM riser height on an 08 YZ450 is?  I managed to bend my bars last weekend and want to replace them.  I bought the bike used and for whatever reason, the PO replaced the bars and risers with 7/8 versions.  I would like to go with fat bars (pro taper contour henry reed bend) and I'm hoping I can use these risers although they appear much lower than what is currently on the bike which looks like about .5" or .75" rise.  They dont list the risers for the YZ but I don't think Pro Taper makes these in a bike specific version.
