I went with the Pac Fab/Tilden crossmember in my 71 K10 5.3L LM7 4L60E swap. I kept the location of the transfer case mount the same. I didn't have to modify the driveshafts at all. The passenger side head is close to the firewall, but does not hit. I ended up using Speed Engineering headers (model 25-1021) because of rear cross member and transfer case. I didn't want mid-length headers aiming directly at the cross member. You can check out my build thread link below if interested. I just finished it up.
