Here's the shroud as is, when I bought the car. It had a 1-1/2" circular hole cut in the top and three 3/4 holes in the side and bottom, all for mounting of the aftermarket electric fan:



And here is how it looks after the welding (and inhaling of melting ABS fumes)



and the finished A/C reinstall (minus the R12).

where did you get the donor plastic? did you use one of those stitching plastic welders?
