I am running the Adams 1350's front and rear and can not say enough good things about the shafts and the customer service I received when that 4X4 parts vendor (that shall not be named) somehow messed up and sent me the wrong shafts.
James the owner of Adams worked with me to get the correct shaft and did it on his dime.
He recommends you go to his web site, learn how to measure them yourself. Then call or email the correct size and have them build it.
For some reason my rear was over an inch too long with an off the shelf set from that 4X4 vendor. James said that he is seeing this.
I never did figure out if the dimensions changed over the years, if I got a set for a manual (dont know if there is a difference) or just what the problem was.
Watch the install videos on their website. Note that this video is for the 1310 shaft. There is a small difference in the 1350s that the rear flange on the transfer case from Adams does not reuse the thick o-ring but the front does.
You will need 3 sockets, some red locktite and a torque wrench. If you cant find the size of sockets needed let me know and I will go look. They are in my rollaway down at the shop. Right now I am :beer:
