Srt10 Dana 60 swap?

I’ve got a chance to acquire a Dana 60 with 4.10 gears and only 32k miles for pretty cheap. It’s from a 2004 ram SRT10. Questions I have are:

1. Does anyone know the width of this axle?

2. Is it worth it to modify this used d60 to fit my ‘69 notch or should I just buy an A body d60 ready to go?

3. From some of the research I’ve done about these I know that it’s a “C clip” d60. What is the difference between a C clip d60 and a regular one?

I haven’t really messed with d60s before. I’ve only had 8.75s
