I have currently on the car the following belts
13x1085 (Porsche part number 999 192 363 50)
13x1000 (Porsche part number 999 192 286 50)
13/12.5x925 (Porsche part number 999 192 306 50)
6PK 858 (Porsche part number 998 192 266 50)
The belts I got from Jeanie are as follows
12.5x1080 (Porsche part number 999 192 335 50)
13x1000 Conti
13x950 Conti
6PK 858 Conti
So the belts with the same numbers is a no brainer. What about the other two. Should I use them or get the correct sizes?
Thanks and have a great weekend.

Bilal,
You should have the following : -
Alternator = 999 192 347 50 - 6PK875
PS = 999 192 286 50 - 13 x 1000
AP = 999 192 306 50 - 13 x 925
AC = 999 192 335 50 - 13 x 1080
For some reason the AC belt on some 90+ cars does not tighten well so we also have a 999 192 335 50A as an alternative which is 13 x 1075.
Hope that helps.
Roger

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission?

And PET shows both-- '266 for a manual, and '347 for an auto (except calls it a 872, not 875).
I understand your preference for the '347

(And if Bilal currently has '266 alternator belt, then isn't that what he needs?)

According to Porsche PET : -
Manual cars 90 to 95 = 266 50 - 6PK 858
Auto cars 90 to 95 = 347 50 - 6PK 872
875 v 872 a readily availabe alternative to the exclusive Porsche size at a lot cheaper price.
Last time I checked Bilal's car is an auto.
Answer Manual v Auto no idea 8>)
There could be for what ever reason some differences in crank pulley.

Thanks to all. The belts fit well. I will crank it in the morning and hopefully everything works fine.
The power steering belt is tight. The adjuster does not give enough slack to get the belt off. I have to undo the pulley on the pump, take the belt off, put the new belt on and put the pulley back on.
