You'll also need the bracket to adapt the Z32 cables to the S13. The ones I have aren't available anymore, but I found this on eBay, same idea:

Here's another pro-tip: Have a dremel or die grinder with a sanding drum ready. The hole on the S-Chassis knuckle where the anchor block mounts will be rusted and needs to be cleaned up.
