Just an idle thought here because I have been looking for a 2nd sliding window to replace my Jalousie window in the driver's side slider: How does the T2 Bay factory middle window size compare to the T3 Wedge factory middle window size? Or are they completely different? I'd like an old style one to match with the sliding window I already have - it would look odd with one old and one new style one like rickyroo has just bought, and I haven't got the dosh for 2 matching new ones.
