alright, so i talked to my buddy who does these diffs and said he'll do em for $65 each. area code i am at is 91910 if you want to estimate how much it would be to ship yours in. the diffs weigh in at 58lbs and a box that would house them is roughly 12x12x16. possibly 60lbs by the time you are done packaging the diff. the diff i have is still up for grabs. first person to secure $ gets the diff.
