    I cannot for the life of me remember if "A" or "B" is the correct way of installing the needles within the slide on a Turbo Seca. I've looked through the manual, forums, parts diagrams and Google images and still haven't been able to find the definitive answer.

    "A" has the screws recessed into the metal plate while "B" has the screws as the highest points on the plate if the images are mindf**k*ng you the way they do me...

    Thanks

    I honestly don't remember since it's been a half dozen years but look at what it's doing....and what the retainer is holding. Ask yourself, does it do what it needs to do if I install it this way?

    I figure things out that way when I've forgotten which way they come out.

    Or, you can ask over here:
