[gmtrucksaddict]

27 spline rear output for th350, asking 75 for it or trade for 73-up CH465 for 2wd, good used needs nothing but paint, i also have adapter, will trade that with the case for a 2wd 73-up 465 with crossmember and pedalsand linkage and rods and Z bar stuff for SBC engines ?
has to have rear mounted crossmember setup not like 67-72 front mounted tranny mounts under bellhousing
