The AC repop spinners are also available here:

They seem to sell out quickly.
The repops have feathers on the arrows while the originals do not.
There were a few other things on 8036 that were not original that you may have noted:
- The wipers parked on the wrong side
- The central mirror was a repop and not mounted as original. More original Lucas mirrors are available
- No windscreen washer jets
- Rear bumper is from a 427 not a 289. Too wide and sticks out too far. Same issue with SPF Mark II's
- Modern wiper motor instead of a Lucas DR3
- No trunk accessories (tool kit, jack, jack handles and holder, bow holder clip, ...)
- No date plate on the McCord expansion tank
Not an exhaustive list but perhaps gives you something to "tinker with".
