Help with Upper Outer Control Arm Seals

[41 Plymouth Coupe]

Hello, I bought a control arm seal kit for my 41 Plymouth and was not able to get the upper outer seals to fit in, too tight. So I trimmed the width and little and ended up tearing one while installing.

The old seals were just fat o-rings and much easier to install, (shown in the photo). I’ve been searching for matching replacement o-rings and have been unable to find any. Does anyone have a source for these? Thanks

I've seen various things used for these seals over the years....large "O"  rings can usually be found at engineering or hydraulic supply shops, also have seen various diameters of radiator hose used, radiator hose of the correct diameter  then cut to about 1/2" in width, the original tool to assist in getting the seals installed is shown in most workshop manuals and works similar to a "shoe horn" which allows the foot or in this case, the seals to slip between the upper A arm and spindle bush.......hope this helps.........andyd

her is the tool used to get the seal and arm back into proper seating. taken from my Miller Tool catalog. Tool number c-736. I have never seen this tool listed on Ebay but that does not mean that someone might have one for sale at sometime.

Thanks for the replies. The o-rings I removed have a wall thickness of about 5/16”, I’ve checked numerous sources and found nothing. Those would be ideal as they are easy to install and are effective. I did a quick search for the referenced tool and didn’t find one, but I did find the attached post where smaller thickness o-rings were used. Seems like the smaller ones will probably work, I’ll try it.
