Low profile roof rack

I was looking to see if anyone has build a custom low profile roof rack for their 1st gen tacoma. I looking to custom build this out of aluminum flat bar and extruded aluminum bars (80 20), as it would only cost roughly $300 to build on that runs the full length of my truck from the roof to back of the canopy. My questions where what grade aluminum flat bar should I buy, and how should I mount the rack to the roof of my truck, I don't mind drilling into the canopy, but would prefer not to with the truck itself. Heres a couple of pictures and links to what I would like the outcome to be like.

Awe ok

I asked because there's a fabricator that makes a ton of custom, 1 off stuff but he's in so-cal

 

Yeah it is.

Has to be the steel wheels; very classic look

 

All depends on if you can weld aluminum or not. Or know someone who can.

Grade probably isn't too important. The stuff you can get at home depot should be fine depending on your design. Just go to McMasterCarr and get the highest grade that fits your budget.

Since it's going to be custom anyway, just some L brackets for the roof mount should suffice.

I know I've seen a few guys use stainless steel rivnuts for the roof (mounted in the gutter) for attaching a rack. Not sure if they had to reinforce it from the inside though. As long as you use copious amounts of silicone, it should seal up fine.

 

Awesome thank you. You hit everything I needed. When summer time comes around I’m going to build the rack for just my canopy and see how it turns around and then decide on what to do about the cab. Here’s a pic of my truck with the current rack. It’s off a 3rd gen 4Runner
