    Tube axle location?

    I have a 32 roadster in that I have put a tube axle on. It is mounted on a 4 bar and will have shorty coil overs laid back and mounted off the axle to the frame.
    It also has a rack and pinion steering set up mounted to the back of the axle so space is at a premium.
    No room for a panhard or small Watts so question is this...
    I have seen a pic on here before(one of brizeys?) of a centre mount tuning fork type thing that locates on a lug on the axle.
    Anyone remember what it's called so I can google image it?.....or any other ideas?

    A mate had a similar thing on a 32,
    it had a threaded boss welded to the back of the tube axle and an approx 1-1/4" sealed bearing bolted to it,

    the front crossmember had a vertical piece of box section welded to it about 5" long with the back face cut off and a slot in the front, the bearing then ran up and down inside the box section to keep the axle central,

    but what its called ?????

    Mike key had one on his roaster pickup, it wouldn't be my choice to use
    Any advice or help given is actually based on having done the job, not read about doing it or Googling it.

    Gary, that's exactly what I was thinking of using(bearing) I assume it worked ok? John that is an interesting pic. Thing is my rack is right behind the axle so location of the "pin" will be tricky but at least I wasn't imagining it!

    It had two problems that i remember,

    the first being that the box section should have thicker wall to prevent it flexing and creating a wider gap,
    the other being a minor rattle, due to the way it needs to work the bearing needs to roll on one side when cornering so it cant be a tight fit.

    I first saw this locator setup about 35 years ago in the states Ross. Simply a bearing mounted on the axle (can be mounted front or back, depending on clearance), which runs up and down inside a channel welded vertically onto the front cross member. It seemed to work pretty well and if memory serves me, Mike Key fitted one onto the front end of his old blue Roadster Pickup ... not on my roadster, as you initially thought!...

    I actually thought it was one of the pics you posted Brizey not your car. Definitely seen one which was like a tuning fork.
    I wonder if a nylon roller would be less clunky? There will be very limited movement in the suspension as this car is set up low.

    Cheers all.
