The primary goal is to just get the seal deep enough so that it doesn't interfere with the tube when mounted back onto the case. The way you check that: if the seal's opening starts to distort at any point while you're installing that tube, the seal needs to go deeper. If it does not distort, and the tube mounts cleanly then, in the words of Dr. Evil "you're golden, be happy."
Stock seals had a shoulder that sat on the lip of the opening, but most replacements do not, I believe. |

Not that I am aware. 914sixer (Mark) had found a stash of NOS and generously offered those last year pretty reasonably, but I think he's all sold out. Maybe there's another source out there somewhere. You can search. P/N 113-311-113-B. |
