1979 280ZX With R180???

[texasz]

I thought that the 280ZX all had R200 diffs in them. Yesterday I pulled the diff from a 1979 and I could swear it's an R180. Can anyone please help confirm for me? Here's a link to a few pix I took of the one I removed: http://www.pape.ws/allan_and_rosanne/Hosted-Pix/Rxxx%20Diff/

Looks like an R200 to me.

It's an R180 that is found in ZX cars that have an auto tranny.....

Odd...this car had a 5-speed.

Someone could have swapped the rear-end out. The 280ZX A/T's had an R180 that was a bit stronger than the earlier types. Clean the top of the case off, and see if it has an"N" cast into the case.

FWIW,

It likely is an R180 regardless of trans type. Scroll down to the '280ZX' chart in this link:

CRAP!!! I wish I had known that before spending the time and effort pulling it out.

Anyone want to buy it? I know, not likely.

Thank you for all the help in identifying it properly.

I have a R-200 .390, I would trade if you were not so far away. Like you I thought this one was what I was looking for.

I wish we lived closer, I'd be up for that trade.

What's the VIN code for a GL in 1979?

It would have the letter 'J' following the S130 in the model description such as, HLGS130JAVBC. I don't know where you'd look for that because that's not the VIN. The VIN won't show the options since it repaces those 5 letters with the sequential number.
