Yeah no problem, I think I'm going to reinstall mine again, go for a little better fit. I would recommend a 1/4" thick weather strip at least. The rail kit does come with some. Also my setup is not compatible with the factory trail rails, it is clamped on
I just installed the TS rails with a Bak mx4 trifold cover. Yes it works. It will take a bit of tweaking and plenty of gasket material to make it right. The rail system sandwiches between the bedrail and the cover, so it raises the cover a bit. It really is only cosmetic. I'll try to grab some pics.
Hey man I have a set of oem Rubi rails, I can send ya the part number an pics tonight. My name's Nate .East metro Stillwater area. Ya can text me at 651-308-4973
