There is no character limit in the text box. Please use full words. The crew here are not kids, or the tech elite. They have all of the answers that you will need, but you have to ask the questions in a manner that makes some semblance of sense. "Assuming your readership is just as informed on the matter defeats the purpose of writing your piece in the first place." A 57 what? Is Tk for truck? If it is, is it a 1957 White tandem-axle tow truck that has been re-powered with a Hall-Scott 1090 inline-6? Err on the side of caution. Assume we know nothing, and give the details.
Read post 9 five times over and then give the exact details of what you actually have. Good fully complete questions with real words rather than text nonsense get real answers rather than wild ass guesses. That is on anything one asks about.
