Question,just so i'm on the same page here

Push beam or Push plate?2 different things,push plate is mounted on the truck,push beam is bolted to the A-frame bot they should have 4 bolts,you only mention 2.
The push beam is typically a tight fit between the A-frame right from the factory and everyone i put together put up a fight so you may need to help it,there's nothing to loosen to help with the fit if we are talking about the push beam.
