I got a few bits years ago on eBay for bugger all. Two nos Bosch indicator stalks and a nos WB Kingswood headlight assembly. Plus the plastic infill that goes between the grill and bumper on a WB. WB 4 speed gear knob as well. All
nos.
I had a nos set of yellow needle quad gauges too. They had one mounting tab broken off. I sold them though.
