Thanks, On the Brakes the AD has the old style long through bolt and nut. The new Brakes require a larger size hole due to shorter length bolt with recessed Allen mount style. Also I am reading that many new Brakes require new levers with return springs. Also the factory Brakes are "Long Reach" and there does not appear to be much of that type available as well. None of this stuff has been easy to adapt to my 1986 SLE.
