I am working on a 2002 Isuzu Rodeo 3.2L where two of the three mounting studs for the cooling fan pulley bracket broke in the block. The vehicle was taken to a shop where they were told they need a new engine, but I am planning on drilling/extracting or re-tapping the holes, but I don't know what the original hardware was for mounting the fan bracket (looks like a water pump but isn't) because it was either lost or not sent back from shop. Are there just three studs, or were there spacers (roughly 2-3") over the studs between the block and fan bracket. I can't seem to find anything on this, diagrams, pictures, or parts to buy, so I'll probably have to fabricate the hardware myself, but I'm looking for the OEM design.

Thanks for your help.
