Finally gave up waiting for someone to sell a rear sway bar for my 2002 Ody and decided to make my own.
It makes the van feel far less front heavy and flatter in corners. All good but could be better.
I decided to start with a smallish 11/16 dia. bar off of a Ford I already had on hand but think I'll go to a 1-1/8 dia bar for the same application.
