Default Is there any way to use an f-body waterpump w/truck alt/crank pulley?

I am going to have a lot of trouble trying to use the truck pump since the outlet points the wrong direction (using stock fbody radiator in my fox swap). Any options here, any way to remove the waterpump pulley on an f-body pump and space it out to line up with the truck stuff?

You can buy spacers for the waterpump (I believe Mast makes some) or you can buy a new 5th gen Camaro waterpump. See my signature build thread link for pics/info on that.

3/4" spacers, under $100 on ebay.
Or swap the pulley. I swapped the pulley since I needed to modify the pump anyway (interference at the heater connections), and I wanted to use a mechanical fan.

I took a cut off wheel and cut the f-body pulley off. I drilled three holes in the truck pulley and used a harmonic balancer puller to pull the truck pulley off the pump. PAIN IN THE ***! I brought my new water pump with truck pulley to the machine shop and they pressed the truck pulley onto the f body water pump for me. I think they had to pull the back cover off the water pump to support the bearing. I welded up the holes once it was on.

I think I would just go with the spacers. This the ones you would need.

Any chance of twisting the water outlet to point the other way? They are just pressed in.

5th gen Camaro pumps line up with LQ4/9 pulleys?? This is awesome, I never knew that before.

Im putting a 102 LSXr on my LQ4 and I got a gen 4 Fbody water pump and spacers off of fleabay and probly also going to use an idler pulley relocator as well. Relocator such as the one in the link below.

If you read the first page or so of my thread, you should find info on buying a $10 bolt & spacer from Misumi USA that will appropriately relocate your idler and save you some money.
