I'd really reconsider the ssqa forks.
I used clamp on forks for a long time because my loader was not ssqa.
You get so much more lift capacity with ssqa forks because not only are they going to be lighter than your bucket + clamp on forks, but you are moving the load MUCC closer to the tractor. The visibility is also much better.
But if you insist on clamp on ones, keep them as wide as you can, cause the outside edges of your bucket is the strongest.
