    In the process of building a low buck AV8. Cobbled together 3 roached V8 banjo rears to make one. In the process mixed up all the parts. Shortened the tube to fit and had the shaft I thought was its mate shortened the same amount I took out of the tube. In the photo I have 1/4' of shaft sticking out past the torque tube bell. Is this in the ballpark??

  2. When you say shaft are talking about auto parts or something else? Hehe.

    In all seriousness, I wish I could help, but this topic is not in my wheelhouse. Sorry.

    ... he said to Milton, just pull out enough to win!:D
    I'm sorry too.
    Considering how many AV8 builds there are on here, the answer should be somewhere, but I hope you get a smart HAMBer with the answer right away, not us smart Alecks.

    Maybe change your title to say
    "How far should drive shaft protrude from torque tube?"
    You'll get fewer dick jokes and more actual answers. LOL

    Over the years of working with banjo rear axle assemblies I have seen the drive shaft flush with torque tube bell end, 1/8 " deep and 1/8" proud. You'll probably be okay.

    Man o man you hang with a tough crowd. Hope you find your answer. I typed and deleted my response a few times. I’ll just let it alone.
    Good luck

    I've done several, usually the chamfered end of the splines is about an 1/8", and thats what sticks out when you lay a straight edge across the bell. Same thing if you look at a stock shaft & tube.

    What you have sticking out now looks pretty much right from memory . Oh wait I can check my 32 PU it has no engine or trans at present. Awaiting a leaking trans rebuild and a mystery heart murmur in the cragar head B4.
