what the?
scoobum asking a question??? lol!
I almost installed one of these once but decided against it since I personally just prefer the hr poly mounts.
I think I remember earl saying he might be concerned with vibration but I would think that would only be if you left some clearance.
I would've probably snugged it up till the rubber touches the frame and then looked at how much the engine twist with the stock motor mounts under acceleration.
I'm not much help, but thats just my 2 cents
