1965 ls2 GTO

I have an LQ4 motor with an LS1 waterpump that is spaced out for the truck accessory brackets. That was done to by the previous owner to install a car intake manifold.

Now to my problem. I bought an air conditioning system and I measured the crank pulley like the instructions said (obviously I got the dimensions for the truck brackets) the brackets don't fit because where it mounts to the waterpump is about 3/4" farther from the head and the bolts are too short to reach the head. On top of that the routing of the belt would run directly in front of the throttle body and would also interfere with my waterpump outlet.

My question is: what would be the proper brackets to use to mount the AC compressor with my current setup.

I would look into the Holley bracket setup. It can be spaced out for any of the 3 different setups by buying the proper spacer for the bracket. If this is all going into a 65 GTO I would look into the complete Holley Accessory setup. Their kit fits the A body cars like a glove.

No AC on mine yet, but it sits high on passenger side.

If you have truck brackets the compressor sits low on the passenger side. Worked great for me.

The stock LS AC setups use a separate, narrower belt that runs on its own groove on the balancer, behind the main belt.
Sound like you have some aftermarket "high mount" AC bracket kit that uses the main Belt ? You easiest option may be to get a truck water pump. That wont fix the belt routing problem tho.
