Originally Long or Short Water Pump?

[DHregdovic]

Did the 67-72's come with a long nose water pump or short? Is there a difference in 2 or 4 wheel drive?

I'm yanking the old 6-250 and dropping in a SBC in front of the 4-speed. The 350 I'm putting in has a short one on it and I need to get all other accessory mounting (alt, pwr steer). I was going to go to the boneyard and find a donor SBC but though you guys could give some insight as to what I should look for to achieve ease of installation.

I was thinking if I were to put it in the 6-250 mounting location and got a 4x4 shroud - would I want long or short. I'm open to other ideas/suggestions. I'm not really worried about stock but rather fit/function...
