The problem is not the water pump, but the timing cover. 69-up are different than 68-earlier.

"once in awhile you get shown the light, in the strangest of places if you look at it right" - J.Garcia

If you are using a 1969 and newer timing chain cover with the longer waterpump you will need to use a 69-70 top pulley. The bottom pulley is the same. You also will need to use the newer alt.
bracket that goes from the waterpump bolt to the alt. it is differant from the 68.

Timing chain covers from 64-68 used the 8-bolt water pump. '69-79 used the 11-bolt water pump. If you have a pulley alignment problem you need the correct depth pulley like the above post said. You will also need a different alternator bracket (from water pump to the adjuster bolt on the alt) since the location it attaches to on the 11-bolt water pump is slightly more to the pass side than it was on the 8-bolt pump. These brackets are sold by PY, Ames, Year One, etc. Your crank, A/C, power steering and alternator pulleys can remain as is.

Here is a link to a page that will explain better:
