I posted awhile back about how one gets the additional caster / camber on a
1999 K1500. I knew that the manual said there were knock outs for the upper control arm that need to be removed in the frame.How hard are they to remove with out the special GM tool? Also are the knock outs on only the inner side of the hole, or is it on both sides of the existing hole?
I want to remove them myself and of course will need to get an alignment ASAP but I also need to drive it there.
Thanks
