This is the distributor off of my carbed 1.8L,, it has the grey spring for the advance curve that is suggested by air cooled forums. I lengthened the original wires with some speaker wire I had lying around. There is very little play in the shaft. Here's a pic. the cap & rotor has very little wear on it. Just drop it in check your timing and away you go. These distributors are highly recommended for performance T4 applications.
