FYI...referring to the additional pics on pg 13 of my webshots. The distance between the inside of the front springs is 24". The distance between the centerlines of the control links is 22" and the depth of the bar is 12". The distance between the outsides of the mount brackets is 14-1/2". The depth of the bar is 12" from CL of where it mounts to the CL of the control link mount hole. The distance from the front of axle (center of I-beam) to front edge of cross member is 16". The bar is 1-1/8" in diameter.
If the spring to spring measurement is 24" and you have 16" forward of the axle to the front lip of the cross member on the 46, the AD bar should be applicable....you may/will not have the predrilled holes in the frame. However, the benefit gained from controlling body roll would make it worth drilling the four mounting holes.
A call to Patrick might also be a good idea as the measurements are from my 54 AD. Hope this helps.
