Is the Thriftside bed a short or long one? The 8' Thriftsides are quite rare, as I recall. Somewhere in that era there is a wheelbase change, with the same lengths of bed but a different location for the axle.
I believe '71 is 120" (7' bed) and 132" (8' bed). It looks like the wheelbase change (119" & 131") is after 1971, likely 1974. Unfortunately I do not have a reference that tells me the '66 wheelbases, and I can't confirm 100%.
