You talking about motor mounts??

 

Yeah. That's the only thing I can think of after the shifter nearly hitting my knee, and the thicker radiator being pierced on one side. Might be wrong but I don't believe so.

 

Have a helper with the brakes applied, goose the throttle starting in 1st gear and then in reverse.You then can look towards the mounts. If the engine moves appears to want to jump out of the craddle, you got a bad mount there. If you find a bad one, replace them all. That is the left, right sides and the transmission mount under the tail shaft.
