That same mount just crapped on on my 92 SSE with 180K miles. Weird sound on acceleration huh? The Chain- sure that will probably work just fine as long as she holds the engine down on the rubber insulator.
These mounts are VERY easy to replace.
Loosten about 3 bolts (can't remember exactly), place flat block of wood under oil pan, and use that as a careful jacking point. The engine should lift just enough for you to slip out the old mount and bolt in the new one. You should not have engine clearance problems while jacking.
My new mount was around $20 for a lifetime guarantee; not like I'd use that guarantee again.
