Yeah for sure. Cloyes billet are nice ones. Hate to say but my Edelbrock one stretched after about 2 years. You can also fit the chain tensioner from the 5.9 motor under an la motor with some clearancing under the timing cover. A new camshaft thrust plate would also warrant replacing as you are...
Do you have a socket the same size you can use to try and push it through. You may also want to try some heat on it to see if expanding and contracting will loosen it up. Make sure to grease the new ones going in just in case you have to do it again.
Honestly DMT has some legit stuff. I'm getting that E body hood pad soon and a couple of other things. I bought the hood yo cowl seal and the metal clips were already in it. A real plug and play item. Much easier than the wiring harness....
