Theres 2 circular seals on the top of my tank. The shop manual calls em roll over seals. I havent dropped the tank yet, and id like to have the parts in and installed asap, because its my dd. This part isnt limited to 1 gen troopers, from what ive seen, this part is used on amigos, pup, troopers, and rodeos. Just want to make sure it is only the seal, and not the valve or cover too.
