E32 old type brake bomb no longer available

I just got the info that BMW discontinued the brake booster 34331162055 = 10.0515-0515.1 ATE. Old partnumber 34331157335
All their stock has been scrapped as max. storage time was 5 years. ATE does not have the production line anymore for this. That is the one used till 12/1990 with ONE connection only, and only used in E32 750.

All parts still available in the net are (very) old stock. Normal lifetime for storage is said to be 5 years.

The other one with one connection was only used on M30 engines

this one does not have the welded on bracket and the connection is different from that of the one for the 750.
The M30 version has a straight connection and the one for the M70 till 12/1990 has a cone type connection.

The one for the V8 RHD and the one for the V12, 34331162055 and 34331162056, will be no longer available.

This is the version for the facelift engine with 2 connections http://de.bmwfans.info/parts-catalog...ke_servo_unit/
A friend in Germany had a look at both versions and his idea is:
I took a short look at both of them. In my opinion old and new style are interchangeable. Use the pipe/connection of the brake booster # 8 + # 9. Close with a blind plug the old connection at the brake pressure regulating valve. See link here
http://de.bmwfans.info/parts-catalog...ke_servo_unit/
What I mean is pipe # 1 which goes into the brake pressure regulation valve. This should be plugged with a blind plug and use the new line and brake bomb with 2 connections from the facelift version, that should be possible.
Important note: as the brake system originally on your car was certified and approved as it is now/original, this modification might cancel your Certificate of Roadworthiness , so all this info is a private opinion and all possible modifications are done at your own risk. Contact your local BMW repair shop and ask them for a solution or how the NLA part should be replaced.
