Thanks for this topic guys... I am working on a 1966 C30 Tow truck. I wasn't sure if I should go out in front of the rear wheels, down in front of the rear axle or out the back.
Out the side might be too loud. Down in front of the rear axle might kick up too much dirt in the yard. Out the back might be the best, but they would not do that on a tow truck. Too much exhaust in the area where they are hooking up.
Oh well.. guess I still have to think about this one!
