I am working on a car that my brother started 15 years ago, sadly he passed away 5 years ago. I am trying to complete the car as I think he would, so updating the rear end is a step in that direction. The kit from Speedway will help in allowing me to mount a Ford 8.8 with disc brakes.

I've used these on a few cars and they simplify an installation and allow use of existing leaf spring suspension for those who are looking to save a few bucks.

DAN I have purchased this item and I was asking if I used the 38" medium spring and have two people setting over the spring area, what would the distance between the brackets be? The car I am making is an open tub. It seats four and no top. no more than 600 lbs on the rear of the car. Thanks I need to order the spring as soon as you get back.

How to mount Trailing Arms on 47 Ford I see in the instructions how to mount this kit to the rear end and spring but how do you mount the trailing arms (I believe that's what they are called the two arms that mount to backing plate on original rear end).I'm going to be installing an 8.8.
