1992 Seville Cylinder Liners

[JO11YAC]

Hi Guys, I have recently purchased a 1992 Seville 4.9L V8 in the UK needing an engine rebuild. I need some O-rings for the cylinder liners I believe but don't know where to get the ones that are correct for my engine. Any advice would be greatly appreciated. 

Regards

Might be GM 12337936. 

Looks like it's discontinued by GM.

See #14.

Thank you for that. All I know for definite is that the car is a 1992 Cadillac Seville 4.9L V8 with Port Fuel Injection. I need the cylinder sleeve o ring seals for it but they are an old part and no longer made. The OEM was 12337936 and from what I have found they were replaced by 01621807. I have searched for both of these numbers and have had no luck (other than some that might be correct on eBay UK). Does anyone know where I could find aftermarket ones or any that would replace the original ones. 

Any help would be greatly appreciate. 
thanks Alex

30+ year old engine. I don't think anyone here has tackled the job. 

These guys seem to know the 4.9 pretty well. About 2/3 down the page they talk about the liners. Maybe a email to them will help figure out some gaskets.

Some '4.9L full block gasket sets' seem to have them. But not certain.

Thank you mate. I found out today that the kit seems to have them as well. Might still drop them an email but thank you so much for all of your help.
