Found boxes of parts.
U joints, ball joints and brake shoes.
92 pickup. I called the local dealership the parts numbers did not even come up.
Ball joints look about the right size but in all honesty i am not sure what 6 inches really looks like.

 

Google the part numbers and see if they cross ref to your truck.
There are more measurements than just the length - like taper on the ball joints.

As far as 6" goes . . .

 

Too bad there's not a diesel in that box of parts

 

It is a Toyota most anything but J**p can be used even if they don`t come close to fitting

 

I would not use any part that didn't cross reference, period. Especially when dealing with critical components such as ball joints. Putting in the wrong ball joints could leave you in the ditch or worse. I'd suggest selling the forklift parts on ebay or maybe to a local shop that works on forklifts. Take that money and buy the correct parts for your truck.
