Re: Frame question.
The Bumper is a 1972 Sierra Grande diamond plate bumper. It is a GMC bumper. Also, the frame partial vin starts with a "2" then "F" so it's a 1972 Flint chassis. the 104 wheelbase tells me it's a Jimmy chassis. The weird part is still the frame extension in the rear. Cut it off and your there. But, it may be something unusual that was not very common. It has not been modified.
Still have not seen any photos of a 72 Jimmy with a big utility bumper on it.
