Thank you, like any new learning curve, I need information. I have heard different things about the numbers produced (somewhere around 140) but even after years of Doo stuff, there is always a grey area. I found out the tunnel number is the same as the block if it is correct. I do need to replace the radiator and will probably need one made. I would greatly appreciate the exact dimensions of the original and if it was left aluminum or painted black. The biggest thing I need is resource books or manuals if anyone knows where I could find them. Thanks for the U2U's and help so far, Ward
