sorry guys, not been on for a couple of days due to being away with no internet access, anyway the comments from Paul has got me worried about fitting it and the one from Andy also gives me cause for concern as for the proof of it being an ST UIM, does anyone have any pics of a genuine ST UIM, that I can compare this one to, just a pic of the flat part where the throttle body fits, so I can see what Andy was saying about the flat face bit and the rounded bit (not that I don't believe Andy) I need to see it so I can go back to the guy I got it from and prove to him it is not an ST UIM....Also I know everyone is commenting on the finish/polish of it...... I can't, and don't want to take any praise for it as it was like this when I bought it...
