Shouldn't be a problem.  The pump design around that area changed in the later years; see the pic below:

Just make sure to keep that semi-circuilar hole on the engine block cleared by passing a wire through it to push out any accumulated gundge when the pump is off the block.  And make especially sure not to block that semi-circular hole with sealant when refitting the pump.

  Yes that's what I was talking about,  Thanks rbm I did make sure it was clear and not blocked... on the new pump there's nothing but flange surface so I put the Sealant as normal..

Good morning Mr. Gumbo! I rebuilt an engine & water/oil pump last year very similar to what you have going on. I remember trying to figure out why nothing I had matched up with the book and other web-based info and stuff. More importantly, my concern was that the weep hole in my engine block didn't match up with the existing pump. I followed the sealant route pictured above, and I've yet to experience any issues; about 6k miles later. Best of luck with your brick!

I've put like 20k miles on a K1200LT pump on my K75 and it's been fine. I got tired of trying to reseal the old one so I just bought a used one off ebay

  Exactly what I did,  only My original oil gear drive is 19 tooth count like the k1200Lt pump so everything lined up perfectly and No More Leaks!!  Thanks F14 for the Original Post.....Gumbo.
