Son was chasing exhaust parts for his Latest, a 63 401 Riviera. Hector's adapter between the Right Exhaust manifold & the Exhaust pipe worked Perfectly, by enlarging the bolt holes slightly. We were told that by Hector before even buying the part. (Appreciate the Honesty Up Front) No more exhaust leaks & don't have to worry about the Heat Riser flap giving a problem when he puts the Sniper FI kit on it. Thanks Again Hector!! JR
Thanks JR for trying and confirming the fitment of the part for the Nailhead exhaust. I'm glad that the part was of help getting another Buick going.
