You have lost your marker lights multiple times due to smashing them? That was certainly true on 40's back when GSMTR was held at Tellico, but it's been a long time since I've seen a smashed one. Maybe Rubicon...
You are correct, the 60 series windows came first, because there was an obvious need for them. The 100's were the second request, so I'm not sure why the 80's got into proto before them. Meh...I think they make tons of sense on a 40 (not with jump seats or factory bar) 60 and a 100. I don't think the sliders windows were easy to open on my 450, and with one of them being fixed, access was limited. Now...compare them to Wes' 70 and you realize the 80 sliders are tiny.
