Been using these for my valve covers with good results. In practice I find that it is best to replace them when I have a cover off but at this price who cares.

Perfect timing for me, as I am needing just this item today for my '83.
However, the link you provided did not give me a specific product.
Got more details?

They are 3mm X 62 mm part number 41KX45

Just got a fresh shipment of gggGarys SILICONE o-rings in, nice and soft just like the factory but a smidge thicker so they seal longer. About 150 sets sold so far, no complaints. Best if you lightly rub a bit of sil-glyde or any silicone product to help them push into the groove as you tighten them. Since there are cheaper alternatives out there now, a set of 4 delivered to your USA door $8
