Hello Johnny,

I really wish I had a list that told me everything that was put on every camper, but unfortunately such a list does not exist.

You were looking at the Snap-In Plug for Lionshead Trailer Wheel Center Caps - Chrome # LHSI60C, which is the piece that goes on the wheel center cap. If your plug measures 2", then the # LHSI60C will fit perfectly. Please refer to the attached image for reference.

If you’re instead looking for the rubber plug that fits into the grease cap on the hub, you’ll want the Grease Cap Plug for E-Z Lube Grease Caps - Qty 2 # RG04-010.

If neither of these options matches what you need, please reply directly to the email with a picture and the measurement of your plug so we can make sure you get the right part.

Have you been able to get out to do some adventuring this summer? Where did you go, what did you see?

Hey Johnny, did you find the right plug for your Cougar's axles? I'm curious to know how it worked out for you, as it could help others in a similar situation.
