well then that guy is high..you can get some on w body store.com for 30+ shipping or zzp 60 + shipping

the stock rubber motor mounts compress when the engine rocks..stock ones esp with high milage are very squishy and have too much play so poylurathane ones are more solid and help when launching your vehicle..helps esp at the track. wbodystore.coms are a not as hard as zzps FYI. people have had problems with vibration with more solid mounts, so i went with wbodystores. poly mounts= better launch, more power to the wheels pretty much,,hope this helps bud
