Car is a Spirit Chassis #4629 I have swapped to the Pertronix LU-281 but can't seem to work out how to get power to the coil. I have attached a photo of the old system Any help would be greatly appreciated! Thanks

I don't know if either of the following will help, but I hope they might. I replaced the Lucas system in LRK37110 with a Mallory Unilite unit and was faced with figuring out how the wiring should work. There have got to be similarities. Here's my annotated image of the Lucas 9BR, where the "outgoing side" notes are what will matter:
Even better, see this post I made on rollsroyceforums.com that includes the above, but larger, and with another diagram that may help you as well. https://www.rollsroyceforums.com/posts/195476/ Brian |

Credit @Wraithman for this diagram, which may be all you need, particularly if you're looking to eliminate the use of the 9BR entirely.
