Getting ready to start a cargo rack for my 80, I'll use it to haul lumber and steel to my shop(not that much) and my 16' cedar canoe. I'll be removing the stock rack and was thinking that maybe I could incorporate the stock mounting points for support. Or maybe I should just seal the holes and go with 3 rain gutter mounts per side? The rack will weigh around 30-40lbs I think, and the most I see loading onto it is 150lbs. Any suggestions welcome, Thanks, Seth
