MG MGA - DM2 and DM2.P4 Lucas distributors
|What are the differences between a Lucas DM2 and a DM2.P4 distributor? What parts aren't common? Is one better than the other? Are there markings on the distributor that tell you what model you have?|
The diagrams in the workshop manual are exploded to different levels making the differences unclear (for me atleast).

|Hi Mike, The numbers are marked on the side of the distributor “DM2” is hard to read though|
According to this site http://www.mgaroadster.co.uk/lucas.pdf (thanks to Steve Gyles), most DM2s are of the P4 ( I only see a couple that aren’t marked “P4”)
According to this site http://www.vintageperformance.com/retrorockets/lucas.htm DM2 have an “older” and “newer” version.
Just a guess here, but perhaps the P4 version is the newer version? (one screw holding down the points)
|I mentioned it to Bob West this afternoon. He did not claim to know the precise differences, but said it is all internal, giving a different advance curve. So that would mean different advance weights and springs I guess.|
