When I did mine I had no problems lining up the bar and getting the bolts in.... getting the bolts out however was a nightmare the bolts sheered in the subframe and when I tried to drill them they hardened and destroyed the drill bit, after about 3 hours a neighbour came out and leant me some colbolt drill bits and his Makita drill, after this I bought my own makita drill and always keep a stock of cobolt bits, they go through butter like hot knife and seem to never give up. Hardened steel, no problems.
The outer bushes were another problem of their own and took a lot of time with a jack to keep pushing the control arm up and down to get the position, really bad design, probably why they moved to drop links on the grande.
