I think if you are repowering with a rat motor or changing the suspension to a modern set up or 4 link rear with big tires, etc, that would qualify to me as high performance.
Another example would be the bear claw latch question seems to me could be an interiors or paint and body. If I wanted to find out about that topic I would look at those forums first.
A starter motor question could to me be electrical. Bed wood or box questions - the bed forum. What you did this weekend, etc, that could easily be greasy spoon talk. But I am not going to start sorting topics and moving them about nor am I going to woof specifically (since this could be considered a woof) at anyone about it. If you think to post in a more specific forum, great, if not, no problem. Better we have the info posted so everyone can learn from it whatever the forum.
It seems that there are more than enough questions for this forum to find out information about the peculiarities of these old trucks. Frame, brakes, transmissions, how to monkey with the okie seal, etc.
However where things are posted are mostly minor concerns at best. I am more worried about language, flames, and rants.
