the lake pipes i made bolt onto my 3/4 chassis - a made special mounting points. i also made up mounts and welded them onto the pipe slightly higher than the bottom so you can't see how they join when you look at it. the usual way is to buy clamps that go around the diameter of the pipe, but i didn't like the fact you could see it easily....
the pipes cost a bit to bend up, because i got it mandrel bent, i didn't want those nasty press bend indents... i had to draw up fully dimensioned plans for the guy to go from as well. (i wanted it to fit exactly)
as far as the wheels go.... if you are using HK wheels i had to do a lot of juggling to get everything to work... see this previous thread:

yours will look great in satin black. make sure you post some pictures....
