Thanks Stretch. I have looked arond some threads to understand how the shaft is attached inside and also what i should expect to find inside the I.P. That thread will also help. B.T.W , I completed the dash recovery. I am posting high quality pictures today to that thread in Interior and detailing. It turned out pretty well for a first timer.
