I am going to stick with the 1 ton springs right now, front and rear. I have been looking at them debating it because of the idea that it will be a stiffer ride, but I still like the idea that they have grease fittings.
The front swap to a 1/2 should not be too difficult since everything except the hole sizes which I need to make bigger are the only difference. The reason for the weight was more from a standpoint of what wheels I wanted to run. I have a set of cragars that are on my 41 buick that I think will be moved over to the truck since the Buick needs to be finished and since they are car tires vs truck tires I was concerned.
