My 1972 GMC currently has the 307 Dana gear and pinion set-up in it and I have located a Detroit Locker with Richmond 373 Gears. These are about 23 years old and have never been used. The previous owner bought them by mistake. He says they are for a 12 Bolt Rear End which is what I need but the serial no,s which are as follows. On the Detroit Locker the No.s are 410408N and A31 with a GM8. Does anybody have the code book for these and could verify the No Please. Thanks
