southwind stringers

I have been looking at the thread in here where he rebuilt all of the stringers in his 85 i believe.It is very helpful but did c.c. have different stringer designs? My primary stringers are great I have drilled maybe 25 holes through the gelcoat and good wood! The secondary stringers are a different story! The only wood left is a thin veneer that is stuck to the glass! The secondary stringers run up right next to the primary stringer and forms a l shape.Does anyone have pics of this or can tell me the dimensions of the lumber? I only have glass and foam left up top!! Thanks guys and gals!!
