i am not real sure on the factory bolts on your truck..but i have used carriage bolts on them, even tack welded them down to a plate as insurance the wont spin.. i drill a hole near the end for a cotter key and use castle nuts.. springs may be a little hard to come up with the proper ones. i have used old valve springs from briggs and stranton motors before

if you cant run with the big dogs...then stay on the porch
