Default what water pump?

im ready to put my engine back in after rebuild and wanted to install new water pump. all the local parts houses replacements have the raised boss or 5/8 shaft. the a/c front bracket mounts to this. has anyone run into this? i need standard boss (not raised) with 3/4 shaft.
72 coupe 350 auto a/c
thanks

This may help go to rockauto site and look up you're water pump look at the picture and if it's the right one use that # to order one.All the auto parts stores can cross reference from one manufacturer to another.

thanks sparky77. i tried looking them up at RA and looking at pics at auto stores. theres a 1/4 inch height difference in the bolt boss, which may be hard to see in the pictures. the more i check into it, seems that 71 &72 had different casting numbers than the others.ill keep searching thanks

Yes....but that should not matter.....
a Corvette water pump is 1/4" longer at the hub with a 3/4" shaft....they were all that way.

Have your auto parts store call technical assistance with these dimensions and you'll get the correct pump.

This is what you're looking for: http://www.zip-corvette.com/catalog/...ater-pump-new/

With or without A/C, same WP (but different bolt kit).

HTH!
