My understanding was that '45 and '46 were the only years that Texas only issued one plate. It took some mild arm twisting to convince the county office that this was the case.
I also had a hard time finding a reasonable deal on a plate. I was very close to buying a pair of '48's that have the same color scheme and doing some hammering to turn the 8 into a 6. Got lucky though and found a pristine truck plate for $50 on eBay, so keep looking.
'69 1/2T stepside, Sea Foam Green, 250 L6 w/ 3 on the tree, not an option on it, in the family since new.
