Axles, VIN and other ???

[Blaze69]

Hey all,
To start things off could someone decode this VIN CKU186F179263, I am thinking that it is a '86.

Next thing is, will the front axle from this Blazer unbolt and mount up the the front end of my '69 Blazer? As you may have guessed I want the disc option that it has to offer. The marking on the donor axle says 44-8F and has a 1 over this number 38996. I'm pretty sure that is is saying it's a Dana 44, but what is the 8F? My axle has a 44-5E or F.

Since this vehicle is going to be stripped I am also looking into taking the Alternator setup also. Does anyone know what rating that model would have? It also is mounted on the passenger side of the engine. How hard will it be to move the current set up on my Blazer over to match the newer one? The brackets are all there and the only problem I can see is where one of the bolts connects to the water pump. I think that its a different type.

I could probably take the air cond set-up, but mine didn't have one to begin with so why mess with it.

Thanks, If someone can verify that it will work I will be doing the change in the later part of December.
