Looking for a measurement

[jameshtaylor]

See the pic. I'm looking for a reasonably accurate measurement of the distance between the two points indicated on the 65-73 front anti roll bar lever shown, i.e. the distance from center to center. Should be 6--8 inches or so. Anyone have one of these levers lying around, or maybe have a car up in the air and accessible? And thanks to someone for the fine image I stole! Jim

The Tarett ones are nearly spot on 6 inches center to center at the softest setting. This dimension should be the same as the one you are looking for, since they are made to fit the same suspension geometry. The 6 inch length gives the optimum kinematics, and is why you should run the bars as soft as possible, using a bigger bar rather than a shorter lever, leaving the lever for fine tuning.

I take it you have the Carrera under A-arm style now, and that is why you cannot measure for yourself?

stock bar on my '67 is 118mm.

Interesting. 4.6 inches.

I should have mentioned that the bar is not on the car- so I guess the softest setting is not the optimal lever position.

I'm getting 119-120mm

Max, yes, I have the "simplified" bar.
Thanks to all. If that arm is 118-120 as you measure it, then my 22mm "simplified" under the control arm bar is roughly equivalent to an 18.2mm thru the body bar by my calculations. There is one other dimension that would alter this... the distance from the control arm axis to the sway bar attachment point. I've been using 160mm. If that distance was actually about 133mm with the earlier thru the body bar, then the ttb equivalent of my 22mm "simplified" bar is closer to 20mm. So I guess I need that number too.
