Yep, that is where I tried to buy them.
But no, this part is special order only, and it takes about 10 business days to arrive. I learned this after placing an order for all the parts, and then after 4 business days they informed me that the clips that were part of the order are special delivery from Germany which takes three additional weeks, and that the whole order was placed on hold. After talking to them on the phone, I got the 7-10 business day estimate for the o-rings. That is why I am looking for alternatives...
Thanks for the suggestion though - Pelican is usually a pretty good source for parts.
P.S.: Ah, I now see my mistake. The two heater hoses (rest of the order) are special Porsche parts - the O-rings are not and ship right away. I assumed all the remaining parts were special ...
Well oping your eyes helps - or having someone open them for you.
Thanks for your help!
