I ordered a ton of seals from Pelican and mistakenly bought two rear main crankshaft seals for a /6. Wishful thinking, I know. These are both brand new and are Victor Reinz, which guys like Jake Raby prefer over the Elring variety.

Please be sure this is what you need and the part number is correct. Selling each for $5.00, buyer pays shipping. Should be able to get it in a small flat rate box, or if you're willing to take the chance, a small padded envelope.
