Guest 1320the260 Posted May 2, 2003 Share Posted May 2, 2003 ok i pulled off the moustache bar on my 2+2 to use on my 2 seater. well after i got all the bolts off on the 2 seater i realised some things... for one, the 2+2 moustache bar was IN FRONT of those big metal pieces... and the 2 seater's is behind them, and second how do i take this one off since that bar is in front??? my car is on jackstands right now and i need help ASAP. joe came and helped me earlier today. thank you! now i need help taking this one off, i don't even know if the new bar will fit... well any help will be GREATLY appreciated. thanks in advance justin Quote Link to comment Share on other sites More sharing options...
stony Posted May 2, 2003 Share Posted May 2, 2003 you are going to have to drop the front of the diff. to do this remove the 4 14mm bolts holding the front member in place, you may also have to remove the driveshaft to do this. once the front member bolts are removed you should be able to move the diff down and fwd off the mustache bar. as ffor is it supposed to be that way im not sure but it dosnt look right.

Dave Posted May 2, 2003 Share Posted May 2, 2003 The 2+2 has a R200 in it and that mustache bar will not work on your R180. If the 2+2 had a good R200 in it why not use it also? Quote Link to comment Share on other sites More sharing options...
stony Posted May 2, 2003 Share Posted May 2, 2003 that is correct i forgot about that Quote Link to comment Share on other sites More sharing options...
Guest 1320the260 Posted May 2, 2003 Share Posted May 2, 2003 oh really?! it IS a R200? remember both of my cars are 74 260Z's my 2 seater is a early model 260, and i'm not sure of the build date on the 2+2 because the plate was removed. this is actually good news because now i have an excuse to bolt up the R200. what do i need to remove to use this diff? will my stock driveshaft bolt up? also will the 5 speed thats in my 2+2 work with the 2 seater's 4 speed driveshaft? your help is GREATLY appreciated! i was planning to swap the diff and tranny anyways... now i gotta go check to see which gear ratio the R200 is. heheh Quote Link to comment Share on other sites More sharing options...
stony Posted May 2, 2003 Share Posted May 2, 2003 are they the same size if its an r200 it will be bigger Quote Link to comment Share on other sites More sharing options...
Dave Posted May 2, 2003 Share Posted May 2, 2003 A R180 has a aluminum plate held on with 5 bolts on the side of the diff just behind the axles, the axles pass through the plate. On a R200 there is not any plate behind the axles. Quote Link to comment Share on other sites More sharing options...
Guest 1320the260 Posted May 2, 2003 Share Posted May 2, 2003 do i need to take the axles off the diff too?? please esplain which parts i NEED from the R200 to bolt onto my car, and which parts from the R180 i can reuse.... Quote Link to comment Share on other sites More sharing options...
stony Posted May 2, 2003 Share Posted May 2, 2003 to swap to an r-200 you will need the diff the mustache bar and the axles that are on the r-200 now. They will bolt up to the stub shafts currently installed in your car. to make it real easy to remove and install i would removed the rear control arm mount too. this way the diff will go striaght up and down Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted May 2, 2003 Share Posted May 2, 2003 I just ran outside and snaped these pics, so I hope it helps... One is showing both, the R200 with matching halfshaft on top of it. Another shows the R180 with matching halfshaft with the bolt through the center to fasten it in the diff. The last one is a comparision of the two side by side.... I hope you can see the differnce Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted May 2, 2003 Share Posted May 2, 2003 crap... they didn't come out so sharp. If you need better pics, let me know and I'll put them in better light.... good luck joel Quote Link to comment Share on other sites More sharing options...

Guest 1320the260 Posted May 2, 2003 Share Posted May 2, 2003 hey thanks! do you guys think i should change the transmissions while i'm under there? my 2+2 has a 5 speed in it... my 2 seater only has a 4 speed. i figure, while the driveshaft is out why not remove the tranny? haha. but then again i don't feel like droppin the exaust just yet. stupid rain, if it wasn't raining right now i'd be out there swapping my diffs Quote Link to comment Share on other sites More sharing options...
