Rebuilt Bosch distributors for my 280SE 4.5 are difficult to find. I was able to purchase a used one and although it came off a 4.5 liter engine has a slightly different ID number. The last three digits are 002 instead of 003. All dimensions and components match, but I am curious what is the difference. I have searched and find VW distributor info, but not MB. Does anyone know where this info can be found?
