Thanks novadude: The blue Felpro rear main seals are actually not bad compared to the "Premium" (and more expensive) flouroelastomer red Felpro seal. It is the worst of the worst. Not that I would use a blue Felpro. They are pretty bad also. I did extensive research on rear main seals for my 327 rebuild I'm working on. It is for my wife's car and I don't want to hear about leaks in the driveway or in the garage. I purchased every rear main seal I could get my hands on (over $300) and compared them all. Hands down the best (not just my opinion but those in the shop) was the SKF 199. Hard to get but it is just was so much higher quality than the rest it just stood out. I found two stores locally that could get it including NAPA. I bought mine from the local independent as much cheaper than NAPA. Follow the instructions on the package to the letter when installing it. DO NOT put it in the cap or block until you have read the instructions at least a few times and understand them completely. Use the shoehorn included in the kit or you will destroy the seal with even a test installation (done that). Use anaerobic sealer from Permatex or Loctite with anaerobic activator or Kleen and Prime on the block and just enough sealer to make it work. Anaerobic sealer is way more expensive than silicone but there is just no comparison in the product but you must understand how it works and its limitations. Techs in the shop love it. Hope this might help you in the future. I can expand on my research if anyone is interested.

I also prefer Victor but as you say hard to get now with the Felpro dominance. Also, Victor seems to be concentrating on imports now that they are Victor Reinz.
