I have a nice show-quality 12-bolt Chevy housing,that has been hot-tanked,blasted,primed,and painted,ready to build.For those that like GM gears,I have mint used 3:31's & 3:55's,or I'll install new gears,any ratio.Aftermarket c-clip axles,or converted to bolt-in axles,with new housing ends.Inquire with needs.price will range from $1,400.00 to $2,000.00,depending on what you want.No disappointments.
