I thought it would be kind of nice to compile a list of part numbers where nobody will have to spend so much time searching the forum or arguing with the guys at Oh'really auto parts on what an Opel GT is.
My knowledge is limited to the 6months I've had an Opel so I'm hoping people will add to this and eventually we will have a really good list.

Opel GT 1.9L Parts List
-Oil Filters
Purolator- L10028 (stock/original filter?)
Fram- PH3614
Fram- PH3887A
Fram- PH966B
Fram- PH16 (larger capacity) <-I use this.
Quaker State- QS3614
Supertech- ST3614
CarQuest- 85374
NAPA- 1374
Mobile- M1102
Bosch- 3330
Wix- 51374
K&N- KNN-HP 1002
A/C Delco ACF-PT-53

-Front Wheel Bearing replacement
Outer bearing Napa PBR1
Inner Bearing Napa PBR4
Grease seal National Oil Seals 1174

-Electronic Fuel pump conversion
Carter p60504
Posi-flo 60104

That's all I've got so far! Everybody add something and after we get a nice thread going I'll compile it into a nice alphabetical list and post again.

Thats all I have for now. If you go to your local part store they will be able to match these numbers to various other brands as well.

Opel GT Brakes:
Rear Wheel Cylinder Beck/Arnley 072-1548
Hyraulic Hose Beck Arnley (2 front 1 rear) 073-1193
Brake hose: Also Raybestos BH36747 which is current stock and correct length.

Upon installation I found the that the diameter of the the hose end is slightly larger than stock. In order to get them to pass through the mounting brackets at each end I had to open up the bracket holes by about 1 mm. Clips worked fine on them.

back up light bulb

Just removed a burned out bulb from the back up light. Not sure if it is original but suspect so. Phillips 12850. Crossed over to a Wagner 6451.

I’ve been in contact with Delco and Remy trying to find alternate part numbers for our opels. I did find another option for a new starter. Remy 16443 is the part number. It will fit 1.9L CIH cars. You can get it at amazon, eBay and several other places. The cheapest I found was Car ID for $50.
