400ex shock mounting questions.

NO!!!! dont mount it upside down, it will work like sh*t because there will be so much unsprung weight on it. Just do it right.
 
yeah, just drill the bottom hole to the size of your stock pin. the top mount is the tricky one, whati did was weld the correct size nuts over the original mounting holes so i dont have any bushings to wear out and zero slop.
