Roof Rack Mounting Points

[greguw]

Hey Guys , I'm just getting into the body area of my build , most of my rust is on the roof of my suburban being a California truck the sun took its toll plus someone thought they could do bodywork ... filled the old rack holes body filler .
The roof could be worst than it is ... I'm just sand blasting the pitted areas to remove as much rust as possible .
I am going to fabricate my own roof rack using aluminum , going for a pretty beefy rack considering I may throw a 41" tire up there ... well lift it with a forklift .
I'm going to ad some inner support plates that are atleast 2" x 6" , just tacked in place with the rack mount bolted thru .
Just wondering if you guys with custom racks did any added supports ?

I'll gets some picks up once the rack starts taking shape .

Thanks guys .
