Looking to swap gears in my silverado and would like to trade or buy a front diff with 3.42s or 3.73s (preferably 3.42s). I can pay cash, card, kidney or trade you my recently rebuilt (3 years 25k miles ago) front diff with the highly coveted 4.10 gears. The rebuild was done by The Rust Lab in Dallas who builds badass stuff. I'd like to find one in florida close to Orlando of possible. P.S. The kidney is probably ruined from years of Ibuprofen abuse, thanks airforce.
