SD Concepts cap and girdle system for B/RB

B or RB? Because they are different.
Just got off the phone with SD Concepts and they state that it is a universal system. When you have your block line bored for the caps if using a RB block they would just bore them to size. If you have any questions on how that is done you can call or email Jerry at Email [email protected]
