Where did you get that ram? Personally I would prefer to have more misalignment on that ram mount. That being said,
Two tabs integrated into the pumpkin should be fine. I would definitely make them as long as you can though. The larger distance helps distribute the stresses. To mount it to the Tie rod, I would make it adjustable. I made something like this for my 60.
BTW, if possible, you want to mount the ram as far (mechanically) from the steering box as possible. If the steering box connects to the passenger side knuckle, you want the ram to attach to the tie rod on the drivers side knuckle. That way, you are using the ram to support the tie rod instead of pushing all of your assist through the rod (easier to cause a bend and failure).
