I think the 3.54's with the OD is just the ticket. That pic is a South African car, Dougs is HST methinks? I believe the difference is male thread versus a female thread holding the whole mess together. I haven't heard of the half shafts ever failing in a CSX, we're talking 1410 u joints doing nothing but driving, in a Jag rear they also hold it off the ground (or are supposed to right David). Your half shafts have to be splined cos they change length.They have a beefy long spline.
