I don't know about where you are, but here in West Tennessee, we have tractor/truck pulls at the fair. They have the usual circuit classes with the real strict rules, but after everything is done, they have a run what you brung stock gas and diesel class. So there is probably a pretty good chance they might. However, with the new diesels, some places are requiring driveshaft and universal loops on all shafts due to liability.
