I have a bit of an issue with my dakota as it has an actual 8 foot box. A bit of an oddity indeed. I have one but the back window glass is broken and they want way to much to replace it. so if anyone knows of one around calgary alberta Canada I'd be interested thanks

 

I see truck toppers all the time on Kijiji here in Ontario, but I don't see too many for an 8 foot box.

The glass should be the same though if you are able to find a topper for the 6'5 foot bed that is the same brand of your 8 foot one.
