Brake booster interchangability 75, 90, gtv6 ??

[lunchcutter]

Hi, I'm looking for a replacement brake booster for my 1986 Alfa 75, 2.5L V6. Can anyone please tell me if the Alfa 90 or gtv6 model brake boosters will do the job here? As I can get my hands on them easier than a 75 one.

To clarify, this part was missing when I bought the car, its not broken.

kind regards,
Greg

The Alfa 90 V6 or gtv6 brake boosters will do the job for sure.

Thanks for the reply, the only thing I'll add is it seems you need to get in through the glovebox area or just above it to the back of the firewall to get to the three nuts which hold it on. Not an easy job.
