Need a little help, installed a disc brake conversion on my 55 bird, brakes are awesome.  My problem is that by doing so it lowered my front end to the point that I can't go over a speed bump without hitting bottom.  Just recently redid the entire steering mechanism and am afraid of busting up my new stuff.  Anybody have any ideas as to how to bring up the bird to normal height, or do I have some worn out gear that I need to replace?  Any help would be appreciated.
