Another piece of the puzzle turned up on my desk this morning. This is the Uni that will couple the steering shaft to the VP commodore steering rack.
It has the Double D socket on it and it is retained with a pinch bolt. Just looking at it I reckon it'll be spot on for the Commodore rack.
I also picked up the belts for the alternator and pump on my way to work this morning. Can't wait to get home and try them all out.
Cheers
