The Dexter Heavy Duty Suspension Kit # K71-360-00 is designed for 33 inch axle spacing. To add your third axle, you cannot simply add a hanger spring and axle. You can keep your 35 inch spacing but you will need to relocate your hangers. I've attached an article to help with the proper positioning of your axles.
You will need to add another equalizer of the same dimension as you have to each side and then add the same leaf springs and shackle straps as what you currently have. You will use the same hanger as your front hanger for your rear hanger. Without knowing what you have, it would be really difficult to duplicate. You may want to consider just using a kit like the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear/Center # APTT5 and the difference in your spring length will account for the difference.
For your leaf springs, you can use the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # e94SR.
I've attached the 5,200 lb axle options we carry to assist with the hub face to hub face length and the spring seat to spring seat measurement on center.
