Where are these things available?

[hougie]

Hey guys, i've been searching the forum all day looking for a couple things and came up with a couple things but not everything i'm looking for. First it frame rails, I understand someone one here ( i believe tamiya cowboy ) sells them. But are there alternatives to buying actual frame rails, Something from rona or something? I'm looking to start my trailer and am on a tight budget for a while (Two root canals). The other thing is tires, I'm looking for grip tires and came across rc4wd in the forums, Are there other places to buy them?
