Contact breaker plate assembly (Lucas 54419327)
Contact breaker plate assembly that mounts the ignition points inside the timing cover.
This is the contact breaker plate assembly, the mounting plate that carries the ignition points inside the timing cover. It shows up in the catalog under the timing cover and contact breaker figure as well as the crankcase and timing gears figure, which tells you it sits at the front of the engine where the cam-driven breaker mechanism lives.

The plate holds the points in position so the gap and timing stay consistent as the breaker cam rotates. If you're chasing ignition trouble, a worn or cracked plate can throw off your points gap even after you've reset it, so it's worth checking the plate itself and not just the points when things won't hold a tune.
Our catalog record ties this part to a Lucas-numbered assembly, and it turns up across several years in our listings. Confirm which contact breaker setup is on your engine before ordering, since the timing cover area went through more than one arrangement over the years.
