Matt;
All Hurst shifters installed by GM were round with the flat sides with HURST stamped into them. When speaking with Mr. Campbell about it, he informed me that GM wanted the round stock arms because they were much cheaper to produce compared to the flat stock arms on the OTC shifters. Campbell agreed that the round stock arms were not as good as the flat stock, but that was what GM wanted - so they made them!
