Assistance with 1971 Opel 1900 Chassis Number Breakpoints

[olmanwinter]

Hello,

 

I will keep this first post to a minimum, to see if anyone might be able to help me.

 

I am trying to help a customer with a master cylinder parts kit for his 1971 1900. The Opel parts catalog lists different parts, according to chassis number breakpoints. After getting photos of the data plate from the customer, I find that the numbers are completely off from the ones listed in the parts catalog. 

 

Are there any members who have experience with chassis numbers on 1960-70s Opels that might be able to assist me? I don't have a lot of experience with them and collected the parts from the inventory of a Buick dealership.

 

Many thanks,
