Pulley/belt issues. Please help me

[Timgoheen]

My 85 will not let belts live with the ac on.
I think the problem is mismatched pulleys, brackets, etc. I beleieve my truck is on a 1988 chassis with a 1988 engine. But either way I have tried different belt configurations , with different belts and it just doesn't work. Both belts basically need to be forced on with adjustments backed off all of the way. Then I tighten them.
What pulleys, or brackets do I need. Please help me.
Thanks, Tim

Here's what it looks like.

The belts are not routed correctly.
The power steering pump belt is middle crank inner water pump and outter ps pump groves.
The ac is inner crank, inner ps and ac compressor.

Tighten the power steering belt 1st then the compressor belt second.

I'm pretty sure that the water pump is in the way if I run a belt from the crank pulley to the ac pulley

 

[Wes Harden]

It will clear, might be hard to fit belt between the crank and waterpump pulleys. Little rotation of belt while fitting on the crank pulley will help

Ac belt is 54.5" long for your truck
