T3 Silver Fascia + Speedo Correction

[mattp]

Are you sure you lose functions with the XR cluster? That document on fordmods only applies to series 1 cars, as I went through this when I tried (unsuccessfully) to put a Tickford cluster into my Fairmont. My understanding is that series 1 had Low(Forte etc), Medium (XR6/XR8) and High(Fairmont/Fairlane/TE/TS etc) series clusters. However, series 2 and 3 cars only had low and high series, and XR models got moved into the high series category as far as clusters go.
I may be wrong, but I doubt it ;)
Ask Janek, he's got (or had) a Tickford cluster in his 'mont I believe.
