So when I picked up the new waterpump on my '89, it came in 2 hub heights
Either 2 1/3" or 3 1/2" (or something like that).

On a '93, do they come in 2 sizes ... or just the 1?
I'm building the engine from the block up and going to put it in a '93 when all is said and done.
* as well, if I go with the '99+ intake, which will require a new PS pump and brackets... will that have an effect?
