944 Ali A arms into 03

[Supa Ninja]

17" is for the 85.5 and earlier half shafts (including the early alloy arms), and 21.5" is for the later 944/951. I really recommend you do your homework before you start buying parts, cause there are several different setups. Superman has a excellent tech article and this very subject, and the search function will take you to several threads about this subject.

Thanks for the info Supa Ninja. By you last comments it sounds like I've got the correct bits. I'm using early pre 86 ali trailing arms ect. Looking through the forumn I took it that the only difference in the rear setups (earlier to later) was the rear hub carriers for the wheels discs, as the ali arms are near enough identical. The later setup had wider hub carriers. Although I could be totally wrong.
