Are the 911SC ROW CIS systems interchangeable for all years?

Can a 1979/80 ROW use a 1983 ROW CIS?

Thank you for any information.

Clarify your question. Do you want to interchange some components, or the whole CIS setup? What are you trying to do?

Yes also the 78/79 US will fit 78 - 83 ROW cars

Edit: looking at that one in the classifieds? That is a steal of a price even more so with free shipping. That can be run on really any SC engine. I have one on my 82US and it runs fine. No lambda to deal with.
