I don't know if the early aluminum trailing arms and the late aluminum trailing arms have the same axle lenght but I think they do. I am using a set of 1987 944-S axles with my stock type 1 tranny and 1987 944-S late aluminum trailing arms. The axles are 21-1/4'' long. They do not bind or bottom out at any point of the suspension travel. They use the VW spline so type 1 and type 2 cv's will slide right on. They are a little thicker in the middle but you can still get the type 1 cv boot over the axle. Hope this helps.
