I had mine spot welded.  I later learned some don't bother spot welding the
upper bushings and experience no bushing rotation, which tells me it can be
omitted if you're adventurous.

This time around I'm inclined to go with Powerflex (
http://t3technique.com/powerflex-bushings.html) for front and rear
bushings.  High-quality marine grease is recommended.
