Cutting edge part numbers

Cutting edge 1-5/8 thick is 2 piece 7J2962. End bits are 1-5/8 7J3461-2 or forged 5J1279-80

I appreciate it, but the corner bits are most definitely left and right specific. That chart only has one part number listed...

You don't know how to read the part numbers. The end bits are 7J3461 AND 7J3462 and the forged ones 5J1279 AND 5J1280!

Odd numbers are for the left side, even numbers are for the right.

I hope you found the proper numbers. My last responses were short and didn't explain why the part numbers are listed in this manner. 
Caterpillar provided customers with the "One Safe Source" catalogs for free. They tried to condense everything to conserve space.
I don't usually respond to posts from my telephone as I try to use the fewest words possible. I hope I wasn't too abrupt.

Not at all. I appreciate the help. I was confused by dashed part numbers as that's not how Cat does part numbers. It all makes sense now.

Thank you for the help 

1J19 crosses to 5J6802, which is a cutting edge consisting of, one 5J6800 and two 5J6806, used on the 53C and 21E.

The thicker version (1-5/8") of that 5J6802 is the 7J2961 (center) and 7J2960 (2 ends)
