Windscreen ?'s

More questions for you guys/gals:

I can't tell of any modifications but this is a 1980 Series 3 109 but has a full size window instead of the split. Is this a normal thing or a Santana thing? I need to replace it and would like to get one of the heated windscreens as next fall it will be in the northwest U.S and in freezing weather. Would a Defender or 110 window fit? I sent off an email to one company with the measurements but haven't heard anything back yet. Thanks

Don't know if it's santana but i have seen series windscreens with the centre bar chopped out and one single pane fitted

A defender screen won't fit, best bet is just to get a series 3 one off ebay
