Sky Silver Topper question...

I have a 2019 Tacoma access cab.Was given a price of 2400. for a new cap in NH, found a Century Ultra (62TC16/2843845 on tag) that was used on a 2017 Tacoma with a six foot bed for $400.00. Will have to drive about 4 hours total and rent a utility trailer to pick it up as no manpower on the other side to lift onto the bed.I have Silver sky ,Color of cap is white. I will paint it black as other folks have done with good result. Trying to confirm that the cap will work before I drive out but having difficulty referencing the above numbers on the cap tag. Any ideas?
