Pacbrake cylinder part number

On my recently sold Expedition, the new owner is experiencing some issues and has traced it back to the Pacbrake Cylinder.

I am going to replace it (as well as the muffler that we noticed had some issues when he picked it up).

From what I can gather on the Pacbrake website, it looks like C11876 is the part number. Does anyone have any experience with this and can confirm that this is the appropriate part number for a 2001 (chassis) ISB?

I'd be inclined to call Pac Brake , and ask for a specification drawing of the part , that drawing would have all the dimensions for you to measure against the part you have.

I replaced cylinder on my Pacbrake PRXB exhaust brake recently. Looks like yours. Part number was on one of decals on cylinder. Called Pacbrake. They gave me current part number. Then sent me to Camping World to order it. Came in a week. $128 including shipping and tax. The part # you list includes clips, one pin and cylinder.
