I can get my hands on an E body 833 but would like to run the numbers past the experts and find out what it is,first off it is supposedly recoed and is painted orange all over and has a cluster shaft with US steel marked on the end,the numbers are as far as I can make out are PP833 2710028 and R21H9G20412 and on the side it looks like a date of 25-1-1,can any one figure this one out?
