340 Rear Main Seal Install with Superformance Seal?

Well I know how that is, but if it makes you feel any better every single one I have ever done (probably 25?) was done once and never leaked again.
But I'll spare you another opinion. :D
I read when I looked them up where they came with installation instructions, but not yours huh?

It hasn't showed up yet so hopefully there will be some instructions. I bought some Right Stuff. I could use that on the ends of the seal instead of the red RTV right?
