help with power steering swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ok... so im trying tpo put power steering on my 70 GMC. its a short water pump setup. i thought a pump/steeringbox i bought awhile ago was for a short pump arrangement, but obviously something is wrong.

i have spent a fair amount of time searching around for info on this and have read alot of stuff, but probably through some fault of my own i have not come up with a good solution.

ive seen people use a 3 groove crank pulley and an offset 1 or 2 grove PS pulley in some configurations. maybe thats what i need to try to locate?(looked into it some but havent come up with them)

you can see how far off my pulley is from ANYTHING.

this shows the bracket i have a little better. there doesnt seem to be a difference between the pump itself regardless of short or long water pump?!

possibly found one piece

second pic down lists an add on 3rd grove(says it is usable with single or dual grove crank pulleys) supposedly for short pumps with power steering

even if that is right, i still appear to need to come up with an offset PS pulley...

This is the correct pulley you need. It's the factory GM part off of a P/S truck with short pump.

With that pulley stacked onto your current lower pulley, your P/S pulley will line up properly without any further mods.

im guessing that is a different part then the gm part #3751232 they had listed in the link? if so, any ideas where i can come up with one?

thanks for the response!
