Just so you'll know, there were two different 25D4 distributors used in JH's with Strombergs. These are identical save that the specs for the vacuum capsule are slightly different. The 'x' in both cases is the revision code for the part, and will be either a blank or a letter from A to Z.
* Lucas 41497x, up to engine number 4802
* Lucas 41584x, from engine number 4803 until the changeover to the 45D4.
I'm trying to fill a few holes in the JH knowledge base, and would appreciate it if you could let me know what markings are stamped into the vacuum capsule of your current (welded) distributor. There should be an 8-digit Lucas part number, such as 5441xxxx, and a set of numbers describing the vacuum characteristics of the capsule, such as 5-12-6 (meaning no action at 5" Hg, full action at 12" Hg, and 6^ total action). Sometimes these marks aren't clear until 30 years of dirt is cleaned off.... Thanks in advance.
