I got lucky on my 70' as it used the larger style ball joints, as do most Z's. But just like Arne said, if the ball joints are the smaller style, just swap out the steering knuckle for the later style. I only add to this forum cause I just dealt with this on my 74' 260Z.

Totally understandable but just remember that those 4" speakers will NEVER trully be "Full range" speakers and will blow up while trying to reproduce low end sounds. The small bass tube will fit behind your seat and give the proper low end that your ears require for a decent sound. Or just get some bigger speakers than 4". Totally up to you though, everybody is usally set in their ways and that's cool but don't expect your $5 goose to go laying golden eggs anytime soon. Dave.

Here's a link to a crossover chart.... http://www.the12volt.com/caraudio/crosscalc.asp Just remember that HI PASS means that the hi's pass thru the Capacitor and block the lows. Low pass Coils allow lows to pass thru and block the hi's. So when the chart says to block frequencies below 100 Hz on a 4 Ohm speaker (like your 4" speakers, Tom) use a 397 uF capacitor to do that. Use Non Polarized caps (available at Radio Shack) and attach it inline with the (+) wire on the speaker. as the drawing shows here... http://www.the12volt.com/caraudio/cross6db.asp Most amps will do this for you with the flip of a switch or turn of the dial. But for an Ampless system, this is the easiest way. The caps are only a few bucks and will save your little speakers. Dave

Tom, I use the internal cross-over in the head-unit as well as the on-board cross-over on the amp to control the frequency that the 4", 5 1/4" and 6.5" speakers get. That's the beauty of the Pioneer head units. They have speaker and subwoofer controls in the audio menu. I can turn the subs on or off, control their frequency and level and the internal cross-over allows me to determine the amount of lows that go into the small speakers. In your case, I would get a small 8" amplified bass tube for your Z. You run a small power wire to it then ground the unit as well. Then run a set of RCA's or speaker wires to it (from the head or directly from the speakers) for signal. This will give the system that "Low end" that it needs and that you've been trying to reproduce with your 4" speakers.Then you can install some non polarized capacitors (about 4.7 Uf or 47? can't really remember) onto the 4" speakers (+) wires and this will eliminate the lows from them. The bass tube has an internal cross over that will block out the hi's. The bass tubes usually have a "Quick disconnect" plug which will allow you to easily remove the tube when needed. So basically, the 4" speakers are for the hi's and the tube is for the lows. You can't rely on 4" or ANY small speaker to reproduce the low ends needed for a decent sounding system. As for your first question, on the roof..... Kinda like a San Francisco police car, "Pull Overrrrrr" I'll be doing a full picture type write-up on the install on the 260Z when I get to that point. As I've never done a 260Z stereo system, it should prove interesting and educational all at the same time. I'll be running new signal and speaker wires from the head unit to the rear in line with the OEM wiring. I'll also be running new antenna control wires, hatch pop wires, hatch pin (alarm) wires and anything else I think of between now and then. Dave. By the way, the less low end that the 4" speakers are trying to reproduce, the louder they will go without distorting.

I put 12 in there last night. I know John has at least 8? he can put in.

We'll call it 70/30 and don't worry, you are one of the "Cool Kids", after all, YOU DO OWN A 240Z. duh. Dave.

HELPED!!! HELPED!!! Is that all I get? HELPED. Just screwin with ya John. Hey Mike, I'm gonna load a bunch into the Audio Systems file. I don't think we had that when I uploaded all my stuff. Fixitman..... What do you have in mind? I have 2) 10" MTX subs in a custom fiberglass box in the spare tire well, 2) 400 watt amps behind the seats, 1) 4-ch to the 6 speakers 1) 2-ch to the subs 2) 5 1/4" 2-ways in the stock rear location 2) 4" Kicker 2-ways in the doors 2) 6" Alpine 2-ways in custom fiberglass pods in the front kick panel area 1) Pioneer AM/FM/CD/XM Satelite Radio head unit. 1) Hidden DVD player with headphones 1) 7" Monitor under the Pass. side dash, that flips out for viewing 2 guage power wire on the battery to the (-) ground bolt and to the 4-fuse distribution block on the firewall. and 4 guage to the amps. 1) custom grounding kit w/ gold plated connectors and terminals that I made cause Z's really need it. Full alarm, power windows, power door locks, H4 lights, LED taillights-front markers-side markers-dash lights-map lights, Cold cathode dome lights and under dash lights, and the list goes on. I'll upload some stuff soooooon, I promise. Dave. *EDIT* I just uploaded a bunch and should show up as soon as they are processed.

And the later models occasionally came with dual vaccums. If you can't find the diagram......... © on the E12-80 to the coils (-) terminal, like normal ( on the E12-80 to the coils (+) terminal Bypass the Ballast resistor by connecting the 2 wires on the ballast to each other (I used a jumper wire from bolt to bolt) And keep the previous dizzy and parts in the storage area just in case. And for Gods sake, carry a tool bag with you at all times, It's a Z, it has as much attitude as a punk rock girl who's eyeliner is running. Dave

I'm guessing that the way film crews take forever to take "the Shot" The Z probably did that shot a few times before they got it right and in the process, the coolant was ready to "swap out" at the time they hit the corner. Questions is how many times they shot that and how long did they amke him wait to do the stunt and how hot was it. Or maybe he lost the lid on his overflow bottle with all the jerking around. Dave.

I think that's what I said? I also put in a link to the exact 15:45 time frame. I was wrong on the correct spelling at first, though. just FYI, Dave

I can't beleive nobody has wrote about the 240Z on the new sitcom "TESTIES" The main guys are in a hurry to get out of town and all of a sudden you see tires squeeling and the camera backs around the corner to see a 240Z sliding around a corner, no swaybar, body roll and twisting as it slides, burning tires and takes off down the road. Then the camera focuses on the two main characters in a P.O.S. Ford Fiesta? Channel 53 on Comcast FX-West tonight at 10:30. Not the episode with the 240Z but a Dumb/Funny show none the less. Here's a link to the 15 second seen. http://vod.fxnetworks.com/fod/play.php?sh=testees&ep=85&start=945&stop=963 Dave.
