leece-Nevile I would believe. Do the lower mounting ears have an approx 1_2" bolt and about 5" spread between the earsIJ How about do you have an energize wire, and how about an idiot light in the instrumentation panelIJ My Alt man always bragged up the leece-Nevile over like the Delco brand, in fact I know I have had a couple large frame leece-Neville's build for my 3408 V-8's, he said they take the vibration a little better on the big 8's. Not that expensive by him, and I know he likes them better than the brushless Niehoff's. He always refers to Niehoff's as the rich man's alternator. Good but not that good for the price. IF you get me the model n I will run it by him, he is an ole retired MM mechanic, so in his day everything was meant to be rebuilt not replaced, and he still achieves it most of the time. Picked up a core from the junk man for my powerstroke, he fixed it for me for nothing. He had to show me last time Chrysler's latest alt pulley, I believe on 2004 and newer the pulley has an overrunning clutch, kind of like the ole MM ampli-torque sprag. People hear this noice and think their alternators taking a dump and sometimes its only this new pulley set up.
