I think you may have a hard time finding aftermarket parts for your bike. It's not that people aren't riding older Shadows anymore. I'd say there probably just isn't a huge demand for aftermarket parts for you bike. Even for my 1997 Shadow, I sometimes have to get creative with what I want to do and adapt parts from other bikes..Nobody rides a 30 year old Shadow anymore?
I'm sure forward controls can be done. But, you may need to do a bit of work to get a kit to fit.
Could you adapt this one to work? (Click image for link)
