source for Bosch alternator diode rectifier pack?

[shogun]

Years ago on my 02/98 M3 the original alternator failed with only 28kmiles, battery light was always dimming, checked with multimeter, only around 10V with engine running, replaced voltage regulator, no change. Finally found out that 1 or 2 diodes had died. Replaced the alternator with a 140A used one since then. Some years ago I tried to disassemble the rectifier to get to the diodes as these are available as single items. But the rectifier pack seems unserviceable, I cracked the housing and had to scrap the rectifier.
Now I am trying to rebuilt the alternator for stock and need a source and a part number for the correct rectifier diode pack, ETK does not show it as single item. I hope someone here on the forum knows a source plus correct part order number.

Data of the original alternator: Bosch 80A , BMW 12311744564, Bosch # 0 120 485 048. KC>14V 50-80A, Made in Great Britain, BMW # 1744562, Accdg to ETK new # 12311744562, 12341234667, remanufactured 12311744566

Checked Woodauto in U.K. if they might have something, but ...apparently not https://www.woodauto.com/group/82/RTF---Rectifier
On the other hand a new rectifier costs usually about $60, a reman alternator might be another option
The same alternator is used in E36 M50, M52, S52, M3 and in E34 with M50 engines

I have used a Benz 190E 2.6 pack before. It is very close in design, specs and operation. I have had two margaritas, so it is a little fuzzy, but I clearly remember that problem in the past.

for future reference: here is a fitting rectifier for the 80A Bosch 0120485048 and the Bosch p/n's from a starter and alternator supplier in Poland, more details on their website for the rectifier https://en.as-pl.com/p/ARC0031
Reference number
1127319009 BOSCH
1127319617 BOSCH
1127319623 BOSCH
1127320862 BOSCH
1127320882 BOSCH

and the pdf file there shows the Bosch alternator number same like my one
0120485048 BOSCH
012048504J BOSCH
0123100002 BOSCH
0123120001 BOSCH

Finally got the correct part number for the diode pack from Germany, original Bosch # for Diode Pack for Bosch alternator 0 120 485 048, KC (R) 14V 50-90A is Bosch 1 127 319 816.
Just for future reference.
Checked the price for the diode pack and gave up to repair the alternator, costs >$50, better I use the defective alternator as core for a reman one, when needed. But still have one more functioning alternator on stock.
