Mine looks like cheap garbage next to yours, but it's infinitely better than the way it came out of the car! I had only two hours to clean it and paint it before hauling it to have it put in my car. Then I found out it's a 6.7 and not a 7.5" like I needed. Yay.

Looks like the diff could have been identified by the rear cover differences. Among other design differences on the housing, between the 7.5" and 6.7".
The rear diff cover on that one there is way different than the 7.5".

Absolutely. However, I freely admit to being a noob about the differences, and having been told "This is an 85 Celica 7.5 diff" by someone with what I presumed was better knowledge than me, I didn't know any better. Having seen them both now, I'd not make this mistake again. =)

I also want to mention that this was for sure an honest mistake by both parties involved - not someone out to deliberately screw me over.

My hope is that people visiting here can avoid the same issue!

Hi All, Wanted to post here that I purchased a rebuild diff for my 92 MKIII back in January from piratetip. I found him over on Supramania this past fall, and we discussed options then. Finally in January he had a diff ready for me. He was very professional in his communications and information provided on the diff. The diff was shipped from him to my home residence and arrived in perfect condition. I finally got around to installing the diff last week into my 92. My original diff had 256k on it, and developed a slight whine back in August of 2019 that was noticeable during acceleration and deceleration, most noticeable cruising at ~ 40-45 mph with some throttle engagement. I also noticed a high pitched whine at higher Hwy speeds of >60 mph. Once the new diff was installed, the whine was completely gone (as expected). I'm currently on about 150 miles on the new diff, and will replace the fluid at about 500 miles using Ford 90 weight and 1/2 bottle of Ford LSD additive. I recommend Nick highly, and if things work out, will likely have him work on a diff for my 86 MKII sometime in the future....possibly installing a tru-trac.

If anyone wants a MKIII diff built with a T2 Torsen, I've just finished up one. :)
