Difference in Check Panels?

[Schniddy]

I have a couple check panels infront of me. On of them is Bosch and the rest is VDO. What years will the Bosch one work with and what years will the VDOs work with?

Thanks
Jon

they should all interchange, I know of at least 4 different styles available threw the years.
