WOW!

Just priced out a set for my 2004 Chopper:
$549 for struts (will have to drill rear fender and move tail lights back)
$189 for sissy bar
$149 for pad
About $887 plus tax; no shipping since they are a couple miles away from me in SoCal.
Very interesting...
however I went with a 2005 Big Dog strut, 2005 metal rear fender modified to fit my 2004 Rolling Thunder, and a low boy sissy bar from eBay for $180 (all Big Dog parts) -- not done yet and will let you know how it turns out and holds up...
Don't know which is better... (my way was/is definately more expensive, labor intensive and requires new paint!)
[my life story in a nutshell ha-ha

Don't see how you can add a sissy bar after the fact for less than $1000.
all things considered...
