What e/tmaxx diffs are these?

[Robert]

I had this posted elsewhere but didn't get much response. Can you guys help?


I'm tearing apart my truck to part it out. I bought these diffs along time ago and can't remeber exactly who made them. They're 7075 alum. So is the cup. The cup has 4 hex screws in it also. Black anodized or possibly powder coated. The coating is very tough. 4 bolts to put the halfs together. The brace is flat at the top and has a set screw in it.

Any ideas who made it? I'm thinking it was hardcore racing. What do you think?
