Hey Jack, the argument is that nascar stuff is not production.... so his truck would not be a modified production body.....
I was responding to 55Chev suggestion to run as a streamliner. Which actually you suggested as well in the 4th post above ( "he could run C/GS")........ LOL>
But for modified pickup body has to be stock ( the usual language about mount position etc etc) which I assume it isn't and it must have the original frame under it which I know is not the case.
I stand by my prior statement that he is SOL other than TO until they make a class....... you know, like the bike guys
