Having trouble aligning the fan shroud holes with the core support holes and the fresh air intake holes. I've removed the bolts through the fender skirts and loosened up the core bolts through the 3rd arm, but it seems that the whole nose of the car wants to be raised off the frame 3/8" more. There are no shims under the core support, maybe a thinner rubber there would gain me 1/8". Do I need to loosen the bumpers or re-shim the front body mounts (the body has never been off the frame as far as I can tell)? What do you think, any advise?
