Thank you for the response. Looked at both the rebuild and the Turner Brake conversion. Big factor was that all for Dunlap four calipers have be machined out and new stainless steel inserts install. The information I have is that it was done by Whitepost Restoration four or five years ago but the pad supports and retainers were not replaced and have since badly rusted.
The cost of new seals and the pad supports and retainers plus new pads, "should be" less than the Turner conversion assume my time is worth zero. Although I will probably eat those words after I have spent time getting the shimming done correctly.
I will post my results, cost and labor when this brakes are back on line. I did not call Myers. Should have been my first call.
Thanks again. You are always a wealth of good ideas and suggestions.
