a833 with 904 yoke??

i actually read that article earlier before i came to this site and they didnt mention anything about a 904 yoke 4spd. lots of good info though. haha i googled all over for this thing and havent been able to find anything. i didnt look at the year on it yet. im going to head out in the shop later and put it up in the air and check the year. whats funny is i have piles of 4 spds in my storage container and this is the only one with the 904 yoke i have. haha luckily i had enough parts to make a driveshaft fit but mostly im just really curious. haha. first one ive seen
