i am hoping to use many of the original fasteners, after tumbling them. 90% seem fine, good threads and damn if they dont (some) look new. difference in steel from 1952 to now?? but since i have collected bolts, nuts and screws from two vehicles might get lucky. my last act was to tumble the whole mess with oil, and they are stored in a box, covered.. The tub that i am going to save has many projects on it, but seems as if most can be repaired/replaced from Kaiser.
