wood bed sizes?

[aceospades]

ok im sure this has been asked before but i cant seem to find it...i need to know the sizes of all the planks in the bed of a swb stepside 1969..i dont have anyway to measure them since when i got my truck it was already removed..im gonna order the stainless strips and my brother in law is a cabinet maker and has access to the wood and he needs to know what size im gonna need..and the best part is the wood will be free and we are using teak..it will never need to be redone as long as im alive after this..thanks
