Bed wood/strip questions

[jdl71]

I have a ‘60 bed on a ‘66 truck. Honestly I didn’t know there was a difference until I bought this bed but I guess the x frame rails were closer together. No biggie. My question is this, when ordering new strips should I order for the frame or the bed? My thought is to match the frame but I want to be sure. Secondly does anyone know if the bed wood classic parts in KC sells is predrilled? It does not say in the description or show any holes in the picture but I would certainly hop it would be. Has anyone used this wood and know if they keep it in stock? I’m only 3 hrs from kc and could pick up to avoid shipping.
