Thanks OldSub. I actually was going to ask if anybody had original measurements in order to either modify or built on from scratch (I work on a steel structure fabrication shop, and while it is not the same, we might come with something nice). I'm trying to keep the buying part as a last resort because a)A new bed is quite expensive. b)buy a used one might be cheaper but shipping will kill me, this applies to a) also. c)I will have to travel the most hidden places around here, El Salvador or even Honduras, to see if I can find a truck from that year, you know Toyotas are king in these lattitudes.
