Worth the trouble?

[1969k10stepside]

Ok,I have 2 tailgates in ok shape but one has the backside smashed in and the other one has dents in the front and some rust under the handle.So,one with a good front panel,and one with a good backside panel (towards inside of bed).--Both better than the average tailgate around here. Would it be worth the trouble to combine the outside and inside pieces to make one tailgate rust,and dent free versues buying a repo tailgate that probably wont handle the weight of what ever I can fit in the truck?Or,try to fix the dents in the one and call it good? Neither have much,if any of a bow to them.How difficult would it be to put the front of one on the other?
