I finished the disc brake conversion today. Well almost. I wanted to swap the centerlink also. Everything came off a 71. My question is where do I drill the holes at in the frame? I bolted up everything. Tie rod ends, Hooked up the steering on the drivers side. Then hooked up the tie rods on the passenger side. The arm (don't know what it is called) that bolts up to the frame is way different than my 63. I have seen this swapped over and was told that you had to drill some holes. I hope I have explaned what I need well enough. Any pictures or info will be very helpfull. Thanks Dustin
