Does anyone know what brand of springs these are? The specs are : Length 12 7/8 thickness 0.440 12 3/4 0.440 12 3/8 0.461 12 3/8 0.461 I bought them in 84 and were never put on a car. The invoice just says "4 springs". There are no markings anywhere on them. And for all of you who are already driving this year, yes the photo was taken today.

Hello all! Does anybody know for a fact wether the INSIDE dimensions- inside diameter and depth (the space where you put the strut insert in) of the Front strut housing is EXACTLY the same as the Rear strut housing? The reason i asked is that i bought a pair of KYB "Ultra SR" cartridge inserts that i put on the 240z`s FRONT, and was wondering if they would fit the REAR. I really dont want to bring down the rear struts and find out that the same or similar struts i have wont fit the front struts. If that happens, we`l have to order KYB`s from overseas, and thats downtime for the Z (express delivery going here together with importation taxes can dr…

I have a production date 5/73 240Z. I just had the car up in the air today to change the differential oil and noticed that there is no rear anti roll bar installed. I see the brackets on either side of the frame but no bar. Was the rear sway bar an option? Can anyone think of a reason as to why this would have been removed. There is a sway bar on the front. I would like to install a rear sway bar but, before I do, I'm wondering if anyone can chime in with any guesses as to why my bar was removed (or if it was even ever there when the car left the factory). If it turns out that I need one, does anyone know of place that just sells the rear sway bar? MSA only sells t…

I recently located a NOS set of 4 Tokico S Series shocks (black cartridge). They are an oil based shock rather than the Tokico H Series shocks (blue cartridge) which are a gas based shock. Has anyone had any experience with the Tokico S Series shocks in terms of comfort and handling compared to the original 240Z shocks. I want keep the car as close to OEM as possible. Thanks, Keith

have my new motor installed in my 75 280 but my front suspension is shot. You push on the front fender ever so slightly and it bounces for hours (give or take). I eventually want to spend my money on adjustable coilovers, but for right now I want something that will hold me off. I need something that will stiffin it up but still not break the bank.

I've been searching for a knock in the rear suspension since I put the car back on the road, following the rear diff swap and rear suspension upgrades over the Winter. Checked and double-checked all bolted connections (I thought), re-torqued the bushing connections, re-checked everything brake related that could be loose. I couldn't find anything loose. Then a light went off......I never torqued the passenger side strut retainer nut down all the way (the one inside the rear hatch area). I finger-tightened it when I was re-assembling, and guess I somehow forgot to go back and torque it down. Tightened it up, no more knock....:stupid: Learn from my dumb-assness.

I been working on the front suspension/steering this past winter and have finally completed it. Everything turned out great and makes a world of a difference when driving. But, let me get to my current issue. I backed the car out of the garage today and there was a noticeable clunking coming from the drivers side rear. It only does when I back up not moving forward. Any idea as what it might be, mustache bar bushing? Thanks

Hey everyone, I just replaced my ball joints and tie rod ends. When I shake the passanger wheel at 12 and 6 there is still a little play, but no movement in the ball joint. Would this be wheel bearings or something? I read about the spindle being worn or the hub out of round, but I'm not quite sure. It is only minimal play, but play none the less. What should I look into? I need to get this resolved before I go in for inspection. What do you think? Thanks, Elliot

I just saw an Official KYB site that says NOT to put ANY oil or liquid inside the strut housing as this may damage the cartridge insert. Says that KYB cartridge inserts are designed to be used WITHOUT any oil or liquid at both high and low temperatures. Another section of the same website said that physical defects of the cartridge outer shell may be caused by frozen liquid (the one you put in the strut housing). I just got through putting bout 4 tablespoons of leftover Fresh ENGINE oil in one strut housing, i hope that wasnt a BIG mistake? Nothings gonna freeze here of course (i live in the TROPICS). So what else can be so bad w/putting oil in the str…

Hello ALL! I accidentally dented a portion of the lip of the original strut housing ( bout an inch, along with a couple of threads) such that the non-threaded portion of the upper gland nut (the one needing a 55mm wrench?) wont even go inside the strut housing, which is to say that i obviously cant screw in the gland nut! I just bought new kyb inserts and dont want to have to order a new strut (GR-2) from abroad (none available here). I plan on taking this to the neighborhood machine shop. Any ideas on how the machine shop SHOULD go about this (the CORRECT way)? And any ideas on how the machine shop COULD go about it (the less correct way) if they lacked…

Where the spring seat on the rear suspension is located, is there supposed to be any kind of rubber insert (or otherwise) in the inside portion of the "hat" (for lack of a better term) on the upper spring seat? Or does it just simply sit on top of the spring and then the rubber spacer on top of it, and finally the upper isolator? Sorry I don't have a pic at the moment.
