part numbers

[mk2 matt]

I know part numbers starting with 909 are rs numbers

But what about 605 any one know?

[chris e boy]

605 were just run of the mill parts mate,introduced early 80`s and applied to parts from fiesta to transcontinental no sequence or model involved just the range of numbers ford moved to after running out of space with the 14.......15...... 16....... 17......... sequence.as you say 90...........were mainly rs accessory parts 50........were mostly std accessory parts but later used on the "motorcraft" branded parts when they were marketed by `enry in the 80`s.

boring but true.
