1968 Race Hemi Vibration Damper

Hi, Looking for a good price worthy dependable damper for my 1968 SS/B Nostalgia Racing Application. Doesn´t need to be the latest super trick stuff, but good enough to handle at least 7500 rpm.
I ask, because as usual, there may be some expensive not so good stuff on the market, but also some less expensive very good, and only you experienced racers know…

Thank you, Stefan
