This is probably going to start off as quite an open question - hopefully someone will be able to give me some pointers.
I have just bought a used aftermarket AC unit for my truck, the compressor and mounts are meant to be for an FE. I have a 390.
In the cab there is an under dash blower unit, which should be easy enough to install.
I also have a cooling radiator for it.
My question is - do these mount in the same way as the stock factory AC did, and if so, does anyone have any good diagrams of assembly instructions.
Where should I mount the extra radiator?
What size bolts should the brackets mount to the block with (and how deep to go?).
Thanks in advance,
Dean

Reason: Spelling
The condenser bolts on in front of the radiator near the bottom.
The compressor mount bolts to the holes in the left head, the idler pulley bracket bolts to the water pump.
I'm thinking the bolts for the compressor mount are 7/16 and should stick through the mounting bracket a min of 1" to 1 1/4"
Looks like the idler pulley bracket will bolt on using two of the existing bolts that hold the water pump on.
Normally this system requires a 3 grove bottom crank pulley that I don't see in the photos, check to see if your engine has one.
We used those York's on service trucks years ago as air compressors. Easy to install since all you needed was the factory AC compressor brackets.They ran for years as long as we kept the oil serviced!

And that's one of the advantages of the York - it has it's own crankcase oil
But in this case, for A/C it might be better to do away with that thing. But if money is short, and you got it - you might as well try it.

Besides being heavy, they are horsepower hogs compared to newer units. Buddy of mine adapted the compressor from a Toyota and the engine doesn't even know when it's engaged.

Absolutely - it's like driving a small two-piston engine complete with crank, rods and pistons. Would you believe the Triumph TR7 (little british sports car) had a York in it? I was fixing mine up and the clutch electromagnet had burned out. You should have seen the face on the parts guy (25+ years ago) when I asked him for a 1977 or so Ford LTD AC clutch and told him what it was for Only difference was it had a two-slot pulley vs. one.
My 78 F150 Ranger XLT has a York compressor on it and it dosent seam to bother it since the gas mileage sucks with or with out it on. I am building a 390 for my 69 and glade to see someone has been able to adapt one of the newer compressors to these older trucks. I have no ac in this 69 F100 and like Dean8020 I will be adding it to this truck. I live in Texas and you need AC!!!
"The easiest way to tell the difference between a York and a Tecumseh is by the type of casting used. Tecumseh compressors are cast iron, and York compressors are aluminum. Both units will interchange for the same applications. Each of the York units can also be identified by the original 2-inch by 3-inch aluminum tag that is attached to the compressor. "
A few other Mustang-centric articles I found say the same thing.

Newer Tecumseh's are aluminum as well. The body lines look a little different to me, but maybe it's just because it's not painted - I've been known to be wrong before.
This is all I've got at the moment, so would like to get it working if I can. - getting suitable things here in the UK is quite difficult (or so I thought, but it sounds like there are a few newer options?!)
In terms of identification, here is the tag
I don't see York or Tecumseh?
I think I only have a 2 groove crank pulley, I will check later.
Will I be able to work out for sure if I need a 3rd groove before getting it on and seeing where it lines up?
I worked on a few factory setups back in the day and that where all pretty much the same.
1st groove was for the alternator and water pump belt
2nd grove was for the power steering belt
3rd groove was for the AC
There where exceptions for models with dual groove alternators
You can hang the idler bracket on the water pump and look straight down the idler fully, that'll give you a good idea of what you'll need.
