Default 1978 pace car L82 oil pan gasket

Guys,

Just replacing the rear main seal and was looking at the oil pan gasket at the same time.....

Felpro seems to have two parts numbers....
OS 34509T or
OS 34510T
(Hope I've got them correct)

Can anyone advise which is the correct one?

Many thanks

I used this Felpro during my rebuild of the L-82:

OS 34510T should be correct for stock oil pan

The Felpro I mentioned above is the one I used on my L-82 during the 2014 rebuild on a stock L-82 oil pan....The difference between part numbers you site above which I did NOT use on my L-82 pan I believe is the dipstick on the drivers versus pass side....
