Skooter You'll get so you can recognize them,was busy trying to gat my 216 to the woods discovered you could grind off the 235 alignment rings flush on the intake so it would then slip right over 216 alignment rings then you could use the whole manifold assembly from a 235 on a 216. That was oh 20 years ago still running. Important to have those rings in there so a hard chuckhole wont knock your manifold loose ! Also I think 235/261 manifolds are virtually the same .
