A few of us CR Sydney locals love this jag upper arm discussion - The CR is supposed to have S2\3 arms, when I got mine they were like yours, and uncle Les helped get me sorted on that as I scratched my head for a while on what way they should go. I believe one of our grand masters (ie. one with a completed car) has the series 1 arms on his, always a fun discussion on which ones are "right"- I think the geometry is probably wrong with either ones though
.
If you dont mind ebay do a search for jag ball joints - I think thats where I got mine. Im too scared to ask at repco for part prices.
