Serpentine Conversion

[blueboykennels]

Okay I've found a 68 SWB that I'm probably going to pick up. My question is on the Serpentine Conversion, I understand that a mid 90's model S10 will use the parts that I will need. Also need to pick up the fan from the S10 as it will be in reverse. My question is one the reverse water pump, can I just use the water pump off of the S10? Will it fit? What about the P/S and the Altenator? Will those bolt up to the 350 block in the 68?
This truck's body is in good shape and runs well and I'm only looking at having to replace one small rust spot in the bed. Other than that very solid truck. But I will have to do the Serpentine conversion and also disc brakes which I'll save those questions for later. The guy will let me have the truck for $2500. Is that a good price?

There is another truck for sale that's $3500, Serpentine Belt already converted and disc brake conversion completed but it has some rust. The dash has a hole about the size of my fist and the rockers are gone. Which truck would you guys go with?

The first truck has a Muncie 4 speed that the guy put in.

Any advice would be appreciated, I'm super stoked about this build and looking forward to learning all I can from you Veterans on the board.

Thanks
