Help with oil pump replacement problem?

Hi,
My first post here so first of all thanks to Guy for the excellent resource.
The engine in question is 131B1000, and it is in a road going Morris Minor 1000. On collecting the car it was showing signs of oil starvation and inspection revealed a fair sized dent in the sump. It turns out the oil pick up is completely snapped, and I have endeavoured to source a new pump.
The OE pump is marked 131AB0A0, 4379253
Fiat no longer seem to produce them and the only aftermarket ones I have found are AE Groups POL 760 and POL716. Sadly on the AE pump casing both bolts go through circular holes, on my Fiat oe pump one bolt is through a circular hole, another through an oval. This means the holes in the casing do not line up with the holes in the block - it's about 4mm out at best. I cannot drill the block as the new hole would 1/2 way acoss the diameter of the existing one - does anyone have any other suggestions or know of a Fiat 131 oil pump with this arrangement of bolt holes - one circular, one oval?
Pictures to follow by tommorrow when I have been up to the lockup with the pumps.
Kind regards,
Gavin
