I'm sure its facing the wrong way in the picture?
Or are you suggesting the lug holes are on both sides? 
TBH I won't know until monday and plus I'm knackard from a hard days work, not on the car though...

I do have some silver solider somewhere mmmmm
Pic is of the back of the radiator, and shows the 4 tapped lugs that the fan carrier locates to, 2 between the inlet/outlet pipes the other 2 on the other end of the rad, what Im say is that if it was my rad, I would not be using the OE fan that mounted to the heavy steel carrier, I would be fitting a "Pacet" fan that secures directly to the radiator core, and therefore no need for the lugs...
Again, if it was me, I would contact the company, and ask if it would be possible to have one without the lugs... as It could be that they are made to order, and not kept
as stock, just a thought... looks a great product though, we have paid 6 times that amount for similar hand made products for our race cars, and baring in mind that materials alone would cost about £40/50 then the best part of a day folding the parts, and TIGing together... bargain
