I agree with dirtydeed - -
If you have QA, you're SO MUCH better off with QA forks over clamp-on.
Clamp-ons stick the load SO FAR forward that you lose a lot of your lift capacity.
QA forks will be more expensive, but much more versatile.
I have clamp-ons for my BX, but I don't have QA.
PS --- you posted while I was typing......My Titans do fit in TWO spots on the PTB.
If you look at a picture of a PTB, there is a "tooth" that is shorter on both sides. My Titans fit there over the PTB, but it is a BX, not an L.....
PPS — this is mine when I had those same forks. Have since sold them to a buddy and got the 30” ones. Better fit for my tractor.
