Not sure on the high angle driveline price but I had mine done at a shop here in town. I happen to know the guy that runs it but he got me a good deal and the price was like 225. That is all one ton stuff on a 208, not sure what yoke is on the 14 bolt but it is stock out of an 86 1 ton. That price was an all new driveline. He traded out the labor so you would be looking at labor on top of that.
It worked great, I'm running a 4 in lift and didn't have to space the T-case down at all on my K5.
