At the start of this project I was warned that the 7 1/4 was not very strong. I went ahead and used it anyway, because I was pressed for time and resources. Just decided I would baby it as often as possible. Yesterday that was not possible, or perhaps it was.. but.. oops lol.
I'm currently looking for a new rear end, spider gears are dead. I'll pass on and reiterate what I was told now that I've seen it firsthand. Scrap that 7.25 and get you a real rear end
