If anybody could refer me to a site where I could buy a new (or used) sprocket cover for a 96 sportster that would be great. Haven't had much luck searching myself.

 

A lot of guys get rid of them so there should be a lot of take offs out there.

 

You can use THIS SITE to look up the part number. Once you have the p/n, try Googling "Harley p/n" (without the quotes).

 

JP Cycles (and probably Dennis Kirk) sells a replacement cover for that type of footpeg mount. Mine cracked years ago when my bike got knocked over. I used the replacement instead of an original and it has worked fine for many years. Not sure if you can run without the cover with that type of footpeg mount, but maybe so.

Here you go:
