It's time to restore the driveshaft on my 1969 GT-350 with the FMX transmission. The driveshaft is the tube in tube type at the axle end of the driveshaft. I can send to Deadnutson but they will replace the axle end yoke since the tube in tube type yoke can't be rebuilt by them. Or, I can attempt to restore the driveshaft using the article I have seen in this forum. If it makes a difference, the driveshaft has 200k miles on it and U joints appear to be the only service ever done. The rubber between the tubes looks solid. From a judging perspective, does either way of restoring the driveshaft make a difference?
