    I am now trying to replace a regulator of DELCO alternator,1987 testarossa(frame numeber 69595,alternator 1101 239 120A 7050 12V).
    However, I do not know the part No. of GM regulator.
    Is GM voltage regulator 1116408 available for my vehicle?
    Could anyone kindly teach me the GM part number?
    At the same time, I want to know how to get the alternator service kit including brush&bearing.
    Please advise me!

    I would think you could get a replacement without much trouble. The internals ahould be the same.

    Hello

    I don't know if it is the same as the one on a Mondial T/348. If yes it is a Delco CS130 and I bought a 1116411 (CARGO 131905, aka D411HD) regulator.

    If you are from USA, I remember having a look at alternatorparts, the D408 you are referring looks to be also compatible with the CS130: https://shop.alternatorparts.com/alternator-parts/general-motors-parts/cs130-alternator-parts/voltage-regulator.html

    I don't remember why I choose the D411, I think I saw somewhere the Delco reference of my alternator directly linked to the D411.

    You can also change all the internals. I will give you my references if someone is interested, please remember than I am talking about a Mondial T/348 alternator!

    rectifier: CARGO 131880 (DR4000HD)

    bearings:
    SKF 6000-2RS-C3
    SKF 6203-2RSH-C3
    (be careful there are two sizes for the front one)

    brush: (I advise taking also the brush holder since mine broke when removing the brush since the plastic is very old)
    brush holder (and brushes): DELCO 10472881
