nczzz. you should post pics of your swap showing mustache bar, control arm hangers, and diff strap brackets, etc. after you complete this. im doing the same swap in a 70. seems theres not a lot of r200/early z specific info out there. or maybe weve both just missed it. good luck. datjunky

ok.. nobody resonded to my post. a bit suprised since there is so much diff talk here. ive pretty well figured out what is needed to install this in my 70.. but what did this come in? from my investigation, it appears to be an r200 with 411 (37:9) . it has a finned cover on it. my best guess is 85-86 200sx turbo? heres a pic or two. thanks.

ok.. im new tonight to this site. and i know this topic has been beat to death.. hence my hours of reading.. i have a early 70 car. i read Jon Mortensen (is this the old school racer?) write up. very educational. but im confused of what i have and how to use it in an early z. this diff was sitting loose in a car i bought years ago. it does have a "finned" cover. it does say 37:9 which equal= 4:11.. right? from what ive read this ratio was not used in the 87-89 turbo cars? so i figure it must be from a 85-86 200sx? but the finned cover? so please tell me what i have.. and help me understand in short what i need to do differently to install in a 70. i am going to use a late zx 5spd. 1) sounds like i should use half shafts from a 300zxt? 2) driveshaft? 3) tranverse piece from any 72 (curved) and on? 4) use r200 rear diff cross member? 5) front mount? im trying to give and get the short direct answers. any info/advice from the old pros is appreciated. heres the pics of what i have. thank you! datjunky
