Also on a more detailed note of fitting the late suspension to the early car. I stated, "the whole late front suspension goes into the early car except the strut bearing mounts". Although it's not clearly pointed out this includes the sway bar from the late car.

Note that the tie rods, steering box, and center rod are the same from 71-74 so these parts do not need to be changed.

Summary, if you have to do the conversion to late suspension on your early car...

strut bearings 71-73
spring perch 71-73
strut housings 74-79
control arms 74-79
sway bar 74-79

Those that already have a 74-79 car just need to put the Porsche 944 parts on, none of this above is needed because your car already has these items.
