I a brand new from GM in the late 60's 12 bolt posi never use. Still in GM box, part number was ripped off from tape sometime in the past. The casting number is EDB 30- 174. We used them before spools in the old days. email me - dtrumhsd@embarqmail.com This was the heavy duty version that Moroso copied later.
