hey guys and gals new guy here with a stringer question

[72V20]

Hi my names Jeff new to the forum and the v20 been working on and around boats my whole life. Ok long story short I just traded my 13ft formal plastics (Boston whaler skiff replica) for a 1972 v20 o/b fisherman. And well this thing needs some serious tlc. I knew from the start the transom was **** but after looking in the buildge area I noticed the stringers were to. I'm wondering if anyone has like a blue print of the hull so I have an idea wat I'm looking at with out cutting up to much of my "new boat". Thanks in advance
