Low miles and/or rebuilt, excellent condition, (good posi, no whine) 3.42/3.73 3rdgen w/PBR's or 4thgen, (LT1 or LS1), within driving distance of Chicago for fair price.

 

got one in the QCA. 3.73, eaton posi unit. drum brakes. 28 spline axels. all out of a 91 formula. im taking it out cause i just got my 9 inch this week. i want 600 for it but price is negotable. does have a little bit of noise when coasting been told this is normal cause its a thick ring gear, done it since it was installed and never gave me a lick of trouble.
