GQ front radius arm on top ?

Hi, am wondering if anyone has flipped the radius arms over onto the top of the axle tubes on a GQ ?
I have a 3 inch spring lift in my shorty and want to do away with the caster bushes. Have thought about drop boxes but they look like a potential hang up point.
I believe that by doing this mod, it may provide a more stable and compliant ride as the arms arent being forced backwards into the chassis before going upwards against the springs.
Is this a viable modification and does anyone have any info ?

used to do this on 80's back before castor plates, or arms, in the 90's, patrols were a little more difficult because of the spring plates so we never did one of those, but its possible, and the arm being horizontal fixes the issues new arms, or castor plates or bushes do not.

If you used the standard nissan arms you wouldn't gain any advantage, the mounting points at the diff end are too far apart, (have a think about how low the rear mounting point would be on the diff if you flipped them) You'd need to use 80's arms or simular that have the mounting points closer together, this is the reason why 80s flex better than Patrols.

no 80 series flex better because of the eye on the chassis end instead of the pin.

wich also points out the problem with using 80 series arms in a gq......... you have to mod the chassis.
or use the arms from a early bundera

so badger, are you saying that to go ahead with this mod, that it would be no benefit to use the 80 arms or is that just because it would be to much playing around to mod the 80 arms to suit the GQ chassis mounts ?

The thing that limits travel in a 3 link front end is as the front flex's it's trying to twist the diff housing, you get more movement from the 80s bushes because they are closer together, it has nothing to do with the design at the chassis end of the arm unless you fit a large lift to a patrol and the pin runs out of downward movment, but even then the main reason is the placement of the bushes at the other end of the arm.
