Hi Jeff,
I think toyota is the same bolt pattern, but the backspacing may be off. The dodge dakota 6 bolt is a different bolt pattern completely.
If I was looking for wheels for your truck I would probably look for any 1/2 ton wheel up until '72 or any 1/2 ton wheel from a '73-86(87?) Chevy 4x4. Those will all bolt on, now you have to find the correct size.
Good Luck.
Correct me if I'm wrong crew.
