I need an Igniton module for my 89 560SL. I have found one but it looks slightly different and has different numbers on it. It came from an 89 560sl though.

The one I found reads 004 545 55 32; EZ0021 ; D117 059
Mine reads............... 004 545 53 32; EZ0017 ; D117 080

Are these parts interchangeable?

Thanks,
MIke
