You need to measure what you have for the true answer.

You need to measure what you have for the true answer.

Usually, O-rings are sized by: O.D. X I.D. X cross sectional thickness, in inches or decimal numbers. All are un-stretched dimensions. Any auto parts store will be able to match up. Elastomer coild be: Viton, epdf, PTFE (Teflon), Buna-N depending on temperature and pressures expected. Just my opinion of course....

You can buy a kit off Muscle Car Research at a very reasonable price.
It has all the seals, o rings and copper washers you need.
