Step Retract Servo Boot Retention O-Ring

[moontownMooney]

Can anyone offer any information regarding the o-ring that holds the rubber servo boot in place on the fixed servo base of the step retract vacuum servo. I have a '68 M20F but I would expect it is similar/same for any model with a vacuum step retract servo. Ours has broken and I need to source a new one. Any info on vendors, part number, material, or dimension is appreciated.

I don't see the o-ring listed in my parts catalog, take you old and have it matched and your favorite o-ring store

I'll check and see if there any reference in the info that Brittain sent me a few years back

@moontownMooney no dice on the specs for the o-ring, might give Brittain a call and see if they can help

If anyone is interested, I was able to get all the details from Cecilia at Brittain. They use a Parker P/N: 2-042. This is a standard "-042" size o-ring meaning 3.25" ID, 3.375" OD, 1/16" bead width. It should be made of N674 compound with a hardness if 70 (N674-70) or equivalent or better. They use Seal Company Enterprises of Tulsa, OK. I found a suitable part matching these specs at www.theoringstore.com

Does anyone know is this the same o-ring size for all of the actuators or just the step?
