8 3/4 Questions

I disagree with the point that 741 cases did not come with 3:55's from the factory. I recently sold a 741 case with the cone style suregrip and it had factory 3:55 gears. They were definitely not aftermarket. The 741 was used until 72 and was retired. The 742 was retired in late 69 and the 489 replaced it. The 741 was used from 64-72.
