Shops that deal specifically with matthews should have a trade policy where you give them you're cam and get the correct one for you're bow, while they keep your old one.
We're a matthews dealer and I know that's how we run the ball game, but it might change if we have to buy a cam from the company.
Some cams have the 1/2 in. adjustment on them, but otherwise you're gonna have to switch them out like the admin says.
