Hello all!

New to the forums, but looking through them I feel this would be the right place to ask my first question.

So, I'm upgrading to PowerSteering; the Netherlands just isn't that big and everybody wants to park their car in a small space. A '56 1/2 ton truck just isn't that small and with 225 tires on the front...you get the picture ;)

Now, the engine is not an original, it's a 1970ish 350CID and it fits, rather tightly in some spots I would say. The PS pump does fit in place, but in order to mount a 3 fold pulley on the crank (the PS would normally use the 3rd pulley on the crank), I would need to cut out part of the frame. Doable, but not something I fancy really.
The question then is, why couldn't I use the water pump pulley (it's a double pulley, closest one already used for alternator)? What would go wrong? Any ideas?

Thanks!
Peter.
