Do the pertronix, I have a set in my 404 unimog (m130 conversion) runs great, I've never had ANY ignition problems.

As for the low front end... shocks really shouldnt really help, they'll just make it ride stiffer. If you haven't replaced your subframe mounts, or know that they have been replaced in the recent past they are more than likely shot, which would result in a low front end.
