Tonight saw some forward progress. Radiator removed, and spot welds for the lower core support were drilled out. Removed core support, and then did a rough fitting of the W203 type fan that @Dave2302 recommended. Put everything together as a cooling "module" as it would be called on a newer car. And test fit everything. Need to fab up brackets, and reassemble this weekend. Looks like it will still be very tight at the engine, with maybe 3/4" clearance from the pulleys. I'll grab pics tomorrow.
