Brian, I checked and it looks like some Entegra's were built on a Spartan chassis which would mean that there unfortunately is nothing for you.
But, if your Entegra was built on an E-450 chassis, then you could use the Roadmaster Exact Center Steering Stabilizer for Ford E-Series # RM97MR with the brackets # RM37MR.
If you can let me know what you have, then I'd be happy to see what we have. view full answer...
