Where to get roof rack mounts for the factory ditch mounts?

I've looked all over for a roof rack that I can actually afford and justify spending money on. I can't drop upwards of $500 on something that I can make at home with the TIG welder and 1" tube bender I already own. I just want something flat and basic to be able to eventually mount a RTT and maybe an awning or some other stuff. I've already got the 1' DOM tube steel and most everything I'd need. I just dont want to make the mounting "feet" that actually bolt to the roof. I don't want to drill holes in my truck, either. I can't find anyone that'll sell me the mounting hardware for a rack except the Smittybilt AM-4, but I can't tell how solid those area and if they'll hold the weight of a RTT. Anybody got any ideas? It's a 2013 DCSB.

 

I have these: https://www.desertrat.com/series-207307-arb-4x4-accessories-roof-rack-mounting-kit.html#!sq=arb rack

The pic on the website shows the basket, but its just the mounting side rails. I used superstrut for the crossbars.

 

sorry for the duplicate photos.. and these mount to the factory holes in the DC

 

Damn those are almost perfect. I didn't realize thats what the ARB one looked like because their pictures suck. Thank you!

 

no prob. they are very sturdy. There are some better pics of the product just out of the packaging somewhere on TW, but cant seem to find it at the moment.

Yep they're exactly what I'm looking for and the pics are great. Thanks so much. I went ahead and ordered them.

 

Here's what I ended up making. I've had my RTT on it for a couple months without any issues other than the noise of having a tent up there. So far so good. I bought a replacement prinsu windscreen for a Tundra and welded mounts on for it because I didn't have a way of cutting one out myself without it looking like junk. I used the ARB rails discussed above, and I have a tubing bender and a welder so I made the rack itself. After making the thing I understand why they're so expensive. I wouldn't make one for someone for much less than what they cost because it's so time consuming.
