The last time I did a Subaru powered 914, I used a Boxster 5 speed transaxle. and had an extra pair of axle shafts made as a spare. I never needed them and I've since closed down my shop, so I have these axles available for anybody interested.
For those that don't know, the Boxster (base model) and the 914 share the same rear wheel bearings. What this means is that you can use the Boxster wheel hub, and stub axle in the 914 trailing arm, which also means you can use the Boxster CV joints IF you have these custom axle shafts to go with them.
What you also might not know is that the Boxster cable shifter will work in the 914 chassis without the need for custom cables. Also, a number of Audi engines bolt directly to the Boxster transaxle without the need for any adapter plate or custom flywheel.
Asking $200 for this pair of axles.
