I have a magnum front cover with all the accessories in a 79 dodge truck that has manual steering and no ac so what I'm looking to do is dump the ac compressor and the ps pump. The ac seems simple enough it's the ps pump that looks to be tricky.

The best solution I've come up with is changing the idler beside the alt from a smooth pulley to a grooved pulley and running the belt over instead of under like factory. My worry is that gonna give the back of the belt enough contact with the water pump pulley to not cause slipping and problems?

The only other solution I can see is moving the alt to where the ps pump was which is some fab work I'd love to avoid since it involves belt alignment.

I do realize the best fix would be just swap to a LA front end but between tracking down pulleys and having to buy a new alternator and water pump I'd rather avoid that.
