Cut out a very basic adapter today out of MDF on the CNC. Test fit tonight before cutting the high dollar aluminum.

Pimp Cim. 
Sometimes it pays off to work somewhere that has cool stuff. Too bad wood and plastic is all we can machine. We have done 1/4" aluminum before but that is about all our machine can handle.Pimp Cim.
Yup. Here’s the spot.
Just to clarify, are you saying that the 19 spline shaft that would go into a split case (like from an H55F) is the same spline as the shaft from an A440F into an HF2A?
I've been back and forth on ordering the adapter plate and modified output shaft, with creating a one off adapter to work off the adapter I have from AA to the split case. With that I could just chop the spud shaft down and do a one off plate to mate them, as long as the ouput from the trans matches the input to the HF2A
Whats the price on the adapter plates from your friend BTW? I had found a place (alibaba) that quoted about $160 USD from china shipped for an order of 5, but hadn't puled the trigger yet.
Yes it seems that way. If you figure out how to adapter the AA adapter kit that would be awesome because the 80 is next in line to ditch splitcase.
As far adapter I don’t know what my friend would charge as he hasn’t told me yet.
I'll let you know. It's next in line.... After the turbo swaps finished, then the one ton swap, and finishing the top mount IC. Maybe and exhaust upgrade at some point too. (Don't wait up it will be a while)
One other thing, as per the thread in the Hardcore section, NWF has said they can do their doubler to HF2A with an adapter, and they said they can mate up their doubler to dometic cases. They didn't say which ones, but they do list a 29 spline shaft in their options. It may be possible to bolt up an NV4500 to an NWF box and buy the adapter from the NWF to the HF2A from them right now.
It looks like $1750, so probably $1000-1300 more than the adapter and shaft in this thread, but you don't have to pull apart an NV4500 to swap shafts, it's bolt up and gives you lower gearing, but you may have to modify fuel tankl etc.

I recieved this from someone with NWF:
"If you look at the Picture on the IH8MUD forum it looks like they used a standard 30* tool and cut the splines that way, it may have worked but its not the proper pressure angle and they will have very little tooth contact. The 19 spline is a very deep spline with a very flat root you can see theirs is not."
It may work, but be different, and may have issues long term, I think maybe it is something to look at though.

What picture is NWF referring to when they say “If you look at the picture on the IH8MUD forum it looks like they used a standard 30* tool...”?
I believe he is mentioning the input gear to the HF2A in relation to the shaft from the ouput of an earlier trans that would go to a split case.
I don't have the parts to look at without dissasembling equipment, but I believe his perspective is that the splines have a different angle to the faces. To really see you'd almost need to cut a slab off both output shafts from a 4 speed manual case and an A440F out of an 80 series.

Awesome! Want me to modify the file and resend? I chucked my parts HF2A a few months back (silly me) so cant modify it and check here but am happy to send to you. You could just print full scale on paper and cut it out to see if I clearance enough.
My buddy was going to pull measurements and adjust the file.
I'm also in for a shaft or two and a plate.

How’s it looking? I’m on the fence for selling my project 80 or doing something fun with it...push me in the right direction please
Nothing happening yet. I’m in no real hurry as my project is only a frame with a cab sitting on it at the moment. His wife is prego with a due date next month so I’m not pushing him.
I got my shaft back from Dutchman today.
Any issues getting them to do it?
Not really. Will sent in his input gear with his and they did ours at the same time. Ended up being $212 or something like that with shipping. I will probably get another one done at some point to have for for the 80.

When are you planning on getting that shaft swapped into the tranny and test fitting everything? Off the top of my head I don't remember if you already part timed the transfer case?
