SS/B Barracuda project

Stefan I sure don't mean to question your intelligience on these cars. You probably know as much or more than 95-99 % of the Mopar enthusiasts regarding these cars. But in case you didn't know, and few young guys don't, back then you couldn't tub a car for S/S and tha class had a tire width limitation. Now on the 'cudas it wasn't much of an issue but on the Darts they had to cut up the sheetmetal to allow for the tires. There was nothing mentioned in the rules that the suspension couldn't be moved, only that it had to be "stock". Mopar, it's its creative minds decided to simply move the springs in 3ins. (hence the factory kits) to permit the larger tires & still remain within the rules. As horsepower increased they discovered the S/S springs were really only good for handling 650-700 hp or so, so the racers began clamping the front of the leaf springs to limit spring separation & body lift. This trick is still used to today by many street/strip cars of all makes but seems to be most popular among Mopars.
As an aside to all this, do you have the Mopar suspension book? It was published quite some time ago & I believe is still availible. Alot of the info is kinda old, but hey, that's what you're working on!

Oh, almost forgot--- the spring relocation was on the S/S cars only
