240 suspension swap
hello everybody. I have a quick question, does 1976 280z suspenssion will fit 1973 240?
|
The ride height will not be correct.
|
thank you for replying. can you give me more info if you don't mind? it will be higher or lower?
|
It will sit higher. The 280Z weighs more.
|
U are perfectly right, but the only difference between 240 and 280 is that the strut mount insulator is about 2" taller on the 280. it can be swap with a 240 one. Strut length is the same, control arm are the same, mustache bar is the same. Thank you again for making me double check. Let me know what you think.
|
And I have another question if you know the answer, I will replace also the diff. from 180 to 200, and the transmission from 4 speed to 5 speed. Do I have to modify the drive shaft? I have a automatic trans drive shaft and a 4 speed one.Also I was trying to install the 1976 280z mustache bar. It looks like is pushing the diff. forward too much.If I installed, my axle will lined-up with the spindle?

differential swap from 280 to 240 issues
hello everybody. I start a new project, and I got stuck. I have a 1973 240z 4 speed transmission. I am trying to install a1976 280z front and rear suspenssion that I build a while ago. I was trying to swap the 180 diff from 240 with a 200 from 280. the 280 mustache bar is diferent. It looks like is pushing the diff. forward too much.If I installed, my axle will lined-up with the spindle? i really need some advices on this matter. Any input it will be highly apreciated. thank you.

So just to clarify... you are using all the 280Z R200 components? Did you mock up everything before trying to install? Are you using the 240Z driveshaft and diff coupler?
Have you checked this? Rear End Swaps For 240Z's |
i have everything from the 280. i tryed but it does not look right for me. i really apreciate your time. I have those instructions. it is just not clear. 😅😅😅😅. i will try again next weekend see how it goes.

You might want to search on Hybridz. Don't ask questions over there until after you search for a while. That is usually the place to go to find out about swaps.

280z to 240z diff. swap
4 Attachment(s)
Hello there.
I need a little help from you guys. I am trying to swap what I think is a R200 differential from a 1976 280z(automatic) into a 1973 240z (manual)I have everything from both cars. For some reason, and I am sure it is my mistake and lack of knowledge, cannot be done. The mustache bar from 280 pushes the diff forward and the front differential mount does not align with the frame holes. Can somebody tell me what the hell am I doing wrong? I am attaching pictures of diffs and mustache bars.Attachment 13366 Attachment 13367 Attachment 13368 Attachment 13369 The diff on the left is from a 1976 280Z (automatic) The mustache bar with red bushings is also from 280Z, the rest is from 240 original parts that I removed . Is any of them an R200? Is there a difference between automatic and manual? |

Merged all your threads. No need to make a bunch of new threads for the same issue. :003:
It really sounds like you are using the wrong parts from "mixing and matching"... Did you fully read this? Rear End Swaps For 240Z's Mustache Bars: See Item #2 in drawing above. (AKA - Differential Case Mounting Bar-Rear) There are three different types of mustache bars used in the 240/260/280Z's. The early Z cars used a flat mustache bar (70/71), when the rear end was moved further rearward with the beginning of the 72 production run, the mustache bar was offset rearward and could thus be described as having an offset. The mustache bar for the R200 found in the 280Z's was further offset by moving the mounting points on the subframe rearward, it is stronger and had larger holes for mounting the R200's larger mounting studs. Front Differential Mount: The R180 and R200 use different front differential case mounts & insulators (see #9 and #10 in drawing above). So it is best and easiest to grab the front mount and insulator, along with the other two parts above (Mustache Bar & Rear Transverse Link Mount) out of a 280Z equipped with the R200. Rear Transverse Link Mount: (Not visible in drawing above - see images below:) The rear transverse link mount runs under the rear of the differential and ties to two lower transverse links (see item #8 in drawing above) i.e. the right & left side, together. Two vertical plates run up from it and bolt to the rear subframe (see #5 in drawing above). There are two types used in the first generation Z's. The 280Z's equipped with the R200 use a transverse link that has a downward curve in it, thus allowing more room for the larger R200. The transverse link mount used in Z's equipped with the R180 is straight and should not be used with the R200. |
yes I did read the article. everything that I have is from a 1976 datsun280z. I removed myself. do I have to pry on the dff. to allign the holes for the front bracket?
|
I have all the parts specify on the article. Still have trouble. I posted some pictures. I was wondering if helps. I am new with these cars, so don't get frustrated. Trying my best. I really appreciate any kind of help

You are installing everything the right way, not sure if even possible, but is the mustache bar facing the right way? How far off are the holes? There should be no difference between the r200s.
