What kind of adapter do I need to go with the Longacre Caster/Camber gauge?

These are what Longacre has...

Big Ford Adapter - 13/16" - 20

Magnetic Adapter
Dunlop Style Adapter
Steel - Blank Adapter - .625 hole

I think just the mag adapter then you mount it to the fixture that clamps to the rim. You will need swivels to do SAI and caster. I just sold a Bear TAC4 with (4) swivels for $1000 on ebay (gave it away!) It took up too much room and I just use a tram to check alignements after I repair frame damage. I am sending out my aligments now ($40 local tire shop) It was not work spending 2 hrs to do myself.

I have the same bubble gauge you are talking about. I've found the magnetic adaptor to be worthless. It doesn't fit through the wheel center to access anything magnetic.

Bobby Archer sold me the threaded adaptor which enables you to screw the gauge onto the center wheel stud. Obviously, you have to remove the center wheel caps to do this. You also have to remove the cotter pins from the two rear center wheel studs.

On my CC, I don't use the center caps on the wheels. This leaves a flat enough surface across the center of the wheel to push the front edge of the gauge up flush against the wheel. I checked my readings against those obtained by using the threaded adaptor. i found no meaningful difference in the readings.

If you study the surface of your wheels, you should be able to figure out what will work, then use the same method consistently.

A word of caution.....I purchased some leveling pads, a laser level and scales from Laongacre also. I assumed my concrete garage floor was reasonably level. I found that my alignment readings such as camber, toe and ride heights were substantially different once I had the car level.
