Rear Driveshaft? Where Do the Accessories Go on Front of Motor?

Alright, I bought a 1986 Power Ram 50 earlier this year and finally joined the forums to ask some questions I have. I bought the truck for $300 with 2 4G54 motors and a 4G52 hooked up to a 5 speed manual transmission (3 motors and an extra transmission why not). I am 17 years old and I am basically learning how to rebuild a motor by myself and it has been very hard to find resources for this truck. First off I have got the motor mostly rebuilt and I am left with figuring out where the alternator and power steering is supposed to go on the 4G54. If someone could get a picture that would be very helpful. My other question regards the rear driveshaft. I recently just looked under the truck and realized, I got no driveshaft. Does anyone know where I could get one for the truck without having to supply measurements for it, or does anyone have the measurements for it so I can get a shop to build one for the truck. Thanks in advance!
