10x2.5 e-brake setup

Trying to round up all the parts to put 10x2.5 inch brakes on the back of my dart with an 8 3/4 rearend. I've seen people mention e-brake levers with a pin type and a lever type. What are the differences between these two? What models did each type originally come equipped on? Are any of the parts interchangeable between these two setups?
