well... I have this and may be willing to offer it up for someone to remake
it is thin plastic, a few cracks in the plastic here and there but I still use it
no holes need to be drilled or mounting hardware needed
they have tabs that slide under the window gasket (see picture 4)
I've been up to speeds of 100mph and they stay on (had to test ya know)
I also have the 1/4 window louvers as well, they stick on w/2 sided tape
I let Mike use my hot pants kit to remake and sell, I guess if someone was interested and serious...
However! I would not trust showcars and bodyparts though... they have a terrible rep for crap quality, slow ship, when there is a problem... back when I was trying to get my 1st hot pants kit I contacted these people, said they had what I wanted but they didn't follow thru on their end. I later looked into this companies history on the net... nothing but horror stories when their name was mentioned. They are also in Canada so us US buyers would have to deal w/import fees? you find a reputable company based here in the US and I'll see if I'm willing to offer up what I have.
