I need four of MRC5016, Bonnet buffer for SIII 109 V8 and early 110. They are available from UK vendors, but I figured I'd look on this side of the pond before I pay for overseas shipping. RN doesn't have them. Link below so you can see what they look like.
I've taken apart my old bonnet and it uses these buffers mounted to brackets on the frame, versus the rubber cap buffers on later Defender bonnets.
