5.3 & 4L60E swap in 72 K10 question

[609thomasm]

So I am planning to start this project soon. I am going to use the advance Adapters kit 50-5310 to mate the 4L60E to the NP205 transfer case.(figure 8 bolt pattern) My question is about the clearance between the CV yoke (spicer) and the transmission. AA states in their instructions that there might be clearance issues. They did not have any specifics and referred me to High Angle Drive Line. They said with my front shaft angle at 15 degrees I am right at the limit. Truck is lifted 4 inches. Anyone out there with this clearance issue? Trying not to spend $750 on adapter kit and installing the shaft in the 4L60E only not to be able to install the front shaft. Thanks for any input.
