Big T,
I'm a little late responding to your post but working on your 61 for 12 years has got to be an "award-winning" commitment. You're the man!
I also have a 61 stepside with about 1 1/2 years on a full out restoration/modification. I love these trucks and enjoy working on mine everytime. I'm blasting the frame at this point but am ready to head back the other way. Once I paint the frame, its build up vice tear down. If my math is right and the money is there, I may finish at 3+ years.
Good luck to you!!!!
