Differences between 2+2 and 2 seater suspension

[theczechone]

I haven't been able to find much on this topic, but I do have a 2+2 parts car out of which I would like to salvage the A-arms as my '70 a arms are beat up. Anyway if anyone has any info on this please share.

I don't have a book in front of me but I'm pretty sure they're the same.

Chuck is correct. Same same. There is no left and right, same part, just flipped.

The 2+2 rear control arms and all 280Z rear control arms are built stronger then the 240 and 260 coupe rear control arms. Also, the front cross member and steering rack are stronger on the 2+2 and the 280Z. Stub axles went to 27 splines with a thicker shaft diameter. Front and rear strut tubes went to 55mm OD with a slightly thicker wall. Rear strut tubes are taller by 2 1/4" and the spring perches are at different heights then the 240 and early 260 parts. Rear upper insulators are 1" taller on the 280Z.

Thank you for this, saves me a lot of time. John have you ever dealt with Fairlady Z suspension? the 2+2 i'm parting is a '75 Fairlady, I'm assuming it's the same as a 280z but I guess I'll find out once I remove it.

[John Coffey]

Not sure about the Fairladys. My post above was about USD S30s.

Yeah I figured as much, well perhaps we'll have more info after I take these down and compare to my 240 assemblies. Thanks

The front and rear springs are slightly heavier, and make a good replacement for the 240 springs, if cut to the correct length. There is probably a sway bar under the rear as well, which should bolt straight on to your 240.The fitting holes are already there.

(At least they were on my 240)
