Red unmarked 6017 or unmarked 6067?

[trains2353]

I need a red unmarked 6067 to complete a set. How does one tell the difference between a red unmarked 6017 and a 6067?

A red unmarked unpainted 6017 would be a 6067... all 6017s were heat stamped(some painted) and did not have arch bar trucks, the 6067 had arch bar trucks(one non-op coupler) & no decoration, and was never painted.

Thanks for the info! Now I know what to look for.
