Drums to disc

I highly recommend to not use the 9" drum spindle. I had one snap right at the root. I was going around a right turn, and the unloaded wheel took off with drum and everything. I realized almost instantly what had happened since I saw the wheel rolling away from me.And since there was a driveway right there onto a parking lot, I wheeled it around up a small hill and plopped the corner down, no brakes required. Then I went to get my stuff.
After this event I researched those 9 inchers some and found that this was not an isolated case. This was on a 69 Barracuda slanty. It happened in about 76/77.
If you want to be steered: I suggest the 73 up V8 disc set-up. Pretty cheap buy-in, excellent stoppers, easy install.
Oh I see it mighta been a V8 car already, so then it will have ten inchers.
