Bob -- Not sure if the Task Force trucks are like the Advance Designs in this regard, but with the ADs, the long boxes (3/4 and 1-tons) are a lot harder to find than the short boxes (1/2-tons) so unmolested and intact bed sides are worth keeping that way. You might be doing a fellow Bolter a big favor if you leave your long bed pieces unmolested, sell them to someone who needs them and do as Tom suggests and get new shorties.
By the way, we get the seedlings for our christmas tree farm from a nursery in your town -- what's the weather like, is the ground still frozen?? When your ground thaws enough for the folks there to dig up seedlings, my season for working on my trucks comes to a halt until Christmas is over.
So ... how much more wrench turnin' time do you think I have???

Regards,
John
