Gary,
I am currently on vacation and won’t be at my hangar until Labor Day weekend. I sent Robert Whitfield a complete set of seals, so he should have the part numbers. All are common O-rings available thru Aircraft Spruce, except the internal gear handle valve and flap selector valve. I found a compatible seal at McMaster Carr that is working fine in these selectors.
I will also reach out to Jim Jones to see if he can send the numbers from our records.
VR, Tom
