Hello Guys -- need some advise have a '69 Hurst Olds 455 4v doing the oil pan & exhaust manifold change with engine not pulled just jacked (looks like it will work) I want to have motor & trans mount just in case. Where should I buy the mounts from I heard that these are replacement parts some work some don't meaning so cause vibration from OEM any suggestions I'd appreciate your guidance since I'm starting this week to work on it need your suggestions asap.
THanks for your help

Unless you can find NOS 402950 mounts, anything else you buy will be the generic 2328-style mount. The aftermarket replacements were designed to be dimensionally correct but may or may not have the correct rubber hardness for NVH. The reality is that this is probably a second-order effect anyway.
