I used a Sears drill.
I cut off the mounting ears on both sides.
I used the mounting off the bottom of the original fan & drilled the holes to mount it 1" left of center (twd drivers side).
I fabricated two mounting brackets for the top of the fan.
I fits like it was made for the TR, but I had a very small interference problem with the PS box - had to grind about 1/4" off the fan shroud.
The TR runs about 10* cooler in traffic.
