Thanks for the responses! Based on the service logs I found, I think the truck has 16770 original miles! Im hoping the fire department it was used at has original pictures of the truck so I will know what it looked like and have a better idea of that is original. If it had a mid transfer case, im guessing that pto pump isnt the original and neither is any of the dump bed stuff? Generator says its a delco remy and I dont see anything behind the grill. Ill do another post on the general big bolts too but keep the firetruck stuff coming!
Thanks
