Is it even worth trying to sell a 741 case??

The 741 case was used quite a bit, I've never used one because most of what I do is drag racing & the small pinion didn't seem to hold up from talking to other racers. I know I'm probably to catch a ratio of stuff over this post, but it's just my opinion & the suggestions from other racers. I've bought a lot of 741 cases to get the gears & sure grips out of them. I've sols some of the 741 cases to fellow Mopar owners that wanted them for their use.
