I wanted to sit the fan behind the radiator so picked up one which is designed to run in either direction push & pull. The fitting kit was not great though so I modified the mounting to run the pull ties directly through the main fan chassis rather than via add on clips.
I also modified the fan itself (left hand side in this picture) to sit cleanly against the front chassis rail in the car:
Something like this - although the springs didn't actually make it to the final install:
This is the result; neat & tidy:
Update - Replaced this fan at approx. 5,300 miles with a large diameter pusher on the front of the rad.
Update - Replaced the radiator at approx 12,500 miles due to leaks caused at some point by the through radiator fixings.
