Every one say's that going to the heavy duty sway bar over 11/16 stock will drastically improve handling. I have the 600 Delphi power gear box on my 63 and as is with small bar ,it is almost against gear box now. I know Phil is putting one on his 63 , and Tom K, for his 62 maybe with stock gear box??????.Do they have the sway bar shaped different over stock or do you have to relocate frame mounting pivot point's???? I can provide picture's if needed.I am speaking of the Addco bar for replacement.
