'79 4X4 400 to 300 I6 swap questions

We are putting a 300 I6 in a 1979 standard cab 4X4 F250 that had a 400 in it.
We have fabbed new motor mount perches on the frame and have the motor sitting where it should be by bolting up the motor to the transmission.
The 300 I6 is from a 1981 F150 so the brackets for alternator and power steering do not seem to fit this truck.
Does anyone have any diagrams or pictures of how these two are supposed to be mounted in the truck?
I am going to need to have a new throttle linkage also it looks like.
The other thing is the clearance from the water pump to radiator.
There is about 3/4" clearance.
Hopefully I can find an electric fan that will fit in there.
possibly going to have to install a crossflow radiator to gain more room.
Any help with these brackets would be much appreciated.
thanks!

I have a 100% original 79 F150 that I'm parting out with a 300 in it. I'll take some pics of the engine/compartment and post them..I have to get some for another FTE member who is doing the same swap anyway.

Still need some info on brackets.
I think I am going out today to try and find a crossflow radiator to gain more room for fans and have the hoses on the correct sides.
Any pics of brackets would help a bunch.
Thanks!

Believe it or not you'd be third in line for brackets off this motor. If I don't work out anything with the other guys I will let you know.

Here's some pics of the 79 F150 4x4 with the 300/6 4-speed. It does have a nice Fisher plow, so the plow pump is right above the power steering pump.
