I'm taking shots in the dark here, but I'd imagine you could utilize a rear swaybar end link, just turned upside down. The ball portion of the link would attach to the control arm, and the bolt portion could attach to the bar itself. One question though, is this bar that you have an upgrade? Because stock FWD 1G bars are only 19mm diameter, while AWD 1G and VR4 front bars are 20mm. It may not be worth it if the bar is stock...
Another thought, the VR4 front bar has a slight "u" shaped bend in the center of it so the driveshaft has clearance to go underneath. I'm not sure if a FWD bar will have that.
Any how, it should be good to run on a FWD galant, you may have to get creative with the link depending on the type of control arms being used, but the bar should be shaped correctly otherwise.
