Who's in the "I broke a 7.25" club?

Decided to sell my 65 Barracuda so I took out the 8 3/4 to keep and put in a 7 1/4. I think it lasted about 2 weeks. Went to lunch one day, launched at a light and bam! By the time I got back, it was locking, binding and hopping. Broke the spider gear and crossshaft. Had to swap the 8 3/4 back in.
