Question:
I bought the demco adapter for my 21 f250 puck system. Can you tell me which spacers to use so I dont have to keep taking the hitch out and take it apart to put the others on?

I wish there was an exact number of spacers to use when installing the # DM6004 but due to variances in vehicles you'll have to trial and error the amount and type to use that will give you the best fit.
