Suspension interchangeability 71/73

[wilson_wwsc]

I have a quick question: Is the suspension from a 71 240z interchangeable with the suspension of a 73 240z? It looks like it will work from what I can tell from my Haynes manual, but I'm not sure.

Thanks

Generally yes. There are differences in hub centerbore, rear anti-roll bar mounts, transverse link bracing, steering arms, tie rod ends, and spring rates.

For the rear suspension, I believe you have to change the moustache bar, longer driveshaft and reverse the diff mount. I'm pretty sure the late '72-73 is when they made this modification to eliminate the vibration from the high half-shaft angles.

I'm sure someone can correct me if my mfg dates are wrong.

Driveline has nothing to do with the suspension. The diff can stay in the forward position while you swap out the struts, springs, control arms, steering, anti-roll bars, etc.

Granted, John.

Just finished 'refreshing' the rear suspension (bushes, struts, springs etc) and would have done the repositioning if I had all the parts (no moustache bar).

Just figured I'd mention it if Wilson had all parts available to fix the issue. Kinda a 'While I'm at it" thing.

I actually have an extra moustache bar and diff mount (i think) from a r200 rear end z. I only bought it because I was just looking at those parts at my junkyard, took it off, and thought, well, I already did the work, might as well buy the part.
