We've tried every version of the aftermarket mounts available on the market. What a mess. 95% are TOO TALL right out of the box, that means the engine will not sit into the frame correctly and the bolt holes for mounting will never line up either. Trust me, it's not something you want to fight with when trying to re-install your engine. Quality and fit are always issues with aftermarket mounts.
Our OE mounts include the steel brackets included and cover already installed, so you know they'll fit right and will last the 20+ years your original ones did.
Yours are partially collapsed, cracked or separated. Time for a new set.
