bed repair did i fubar the bed

[niterider65]

I don't know if this is where it should be posted here or in paint&body?
any way it dawnd on me that i drilled out the l brackets on the bed that hold
the wood in place because of they rusted a way .. any way the new angles i
bought are stainless steel .. if i weld them in and its bare metal on the back side what can i use to keep it from rustingunder the stainless steel or blistering the body work i have started and need to slick to finish .. I had a freind say blot them in. i thought about it for a min and then i though if i bolt them in how can i hide the boltd from being seen on the out side of the bed . I know the step will hide most but not all .and if i dont mount if in the front and rear of the angle to the bed it could roll. or am i blowing this out of the water ?
The other thing is to just put a metal bed on it >. any one have or had this problem ??? pics of the fix would be helpfull 3
Thanks for your time
sorry if i rambled
