    Outfit called Amsco Valley Forge (In NY) may be worth looking into. We do vintage auto and restorations and occasionally use them. One of our mom and pop parts suppliers was looking for a leece neville and i gave him the link and turned out they had it!

    Their techs are also really decent!

    You can get drop in fit 12 volt Prestolite/Leece Neeville 140 amp alternators which should fit the 27Si mounts. Even have isolated negatives and indicator lamp support.

    If they were only less than $200 each.

    The Delco 27SI have an SAE J180 mount. Of course you have to find the pulley and belt to match. Most Leece Neeville/Prestolite have isolated negative plus adjustable voltage.
