I have a 72 Duster with the KH SBP and am interested in doing this swap. Anyone in or around the Toronto Canada area had the machine work done? How is it going with those who have done the swap. Any problems after use?
Sorry I can't help you when it comes to recommending a machine shop in your area but if you read through this thread you'll find a few things that people have encountered with the swap. All things said and done it has been a relatively easy, inexpensive, and effective way of getting the 4.5" bolt circle while maintaining the KH brakes. The key to the swap is a good machinist.
