removing spider gears 7.25

I had a 1981 Dodge Marida 318 auto that had a 7 1/4 2.20 open. It had C clips.

But the 30 or so 1961-74 7.25's I've had the covers off, all were NOT c clip.

I've had a few 7.25's with Suregrip, One held up behind a 9.5:1 360 4 bbl 727 auto, 3.23:1 ratio.....
Never was stupid enough to try a gravel burnout onto pavement. Just saying......
