So trying to clean out my garage today and found another one of these. Super early spider Rear velocity adjuster with built-in site rail. This is New Old stock. Only those with refined tastes and great humanitarians would find this collectible. 30 bucks shipped to your door. USA

These are great. Here's what it might look like fitted to your Spyder.
