you have to grind the water pump housing for the 4 locating "teeth" on the csi(which is a good idea i think),NOT a big deal. also you might have to enlarge the stock opening a bit along with cutting the grooves in.
Also the fan shroud needs to be trimmed.

My CSI went through 2 years of daily driving with no problems. I know enough friends that have gone through multiple Mezieres to NEVER buy 1 for the LT1,very shoddy quality IMO.

 

You had to trim your fan shroud? I have plenty of clearance with mine . Do the '93's have different fan shrouds?
