License Plates #'s

[mjgord51]

I am wondering out there if any body can give me the correct numbering/ letter sequence for a 1968 C10 LB for the license plates. Mine is a tad bent up and I only have the rear front is MIA. I would like both I have found very little sets out there, Mine starts out two numbers,space, three numbers, space, one letter. I have seen two trucks one 68 and one 69 with plates mixed up, both found on the"net" start out with one letter, space, two numbers, space, three letters. also found some on Ebay the mixed up way. DMV is a waste of time due to the fact the age of it, don't know if I try a different person behind the counter might get a different answer. ANY help would be great. Thamks, mjgord51
