4 link rear set up for 69 Dart GT with a 9 inch

I'm wanting to convert my rear end to a 4 link set up. I am currently running a standard width 9 inch and factory leafs.

If someone has a set up they are not using in would be interested in talking to you. Looking preferably with the narrow setup if in the future I do narrow and mini tub which is actually the plan.

I've had some good luck finding some quality parts on here so fingers crossed this works as well and I don't have to blow the budget looking elsewhere.

Thanks in advance
