I just picked up this cap on FB Marketplace. It is a leer 100xl on my 13 tundra. I'd like to put a canoe rack of some kind on the roof. It has these rails. What kind of rack would work? What's the cheapest place to to get rack system parts. I think I just need the uprights and crossbars? Anyone recognize this rail type? They might be thule. I don't want to pay $800 for a rack on a $400 cap.
