Hello, new member here. I'm in the US and as you know, Skylines are just becoming legal here and I was able to scoop one up. I'll admit, I'm not super knowledgeable with the ins and outs of these cars and come from the Subaru world prior to this. Anyway, I purchased a 90 gts-t and was told that the rear diff is pretty aggressive although the importer couldn't tell me what it was. It doesn't seem to be welded going off of my limited knowledge. However, it's pretty annoying honestly (very loud and rough around turns) and I don't plan to track the car or do much more than regular driving, so I plan to just grab a stock rear diff instead. I was hoping to find out what diff is currently on the car though to ensure no strange swaps involving the driveshaft and such were done so I know that what I purchase will fit. Not expecting anyone to know what's going on inside the casing, but rather just want to know if this is a r32 gtst diff or if it looks swapped. Looked at a good bit of photos of others for sale trying to match one up but not having a ton of luck.
I've attached a couple of photos I was able to grab when looking under the car. If any additional photos or info would help in identifying, please let me know and I'll follow up. Appreciate any help!
