Is This a Lestek Alternator?

[Vintageracer]

Pictured below is the alternator I just removed from my 1990 FHP car. The alternator is externally regulated and for all purposes is a GM Delco Remy (DR) alternator without any DR markings. The harnes to the alternator looks original and not modified. The mounting brackets look original with no modifications. This alternator uses a GM type plug with 2 terminals and the 1 power output connection. There is also a ground connection on the back of the alternator. There is only one stamping on this alternator. That stamp is on the plate that is riveted to the alternator case and that number is 14665.

The case is EXACTLY the same case used by GM up until about 1970 when they went to internally regulated alternators for all vehciles with the exception that the case has a machined area below the small bolt mounting tab which is where DR put their numbers. This machined area looks original and not something added later. I just went the the parts store and the alternator the computer AND hard cover books call for is the standard Ford Alternator.

Since I cannot find any information on this particular alternator and I remember everyone talking about a "Lestek" alternator I thought I would post here and get the real answer.

I will try to have this alternator rebuilt. Any input as to if this is a Lestek or if not what type of alternator this really may be is appreciated.
