Those springs are exactly what I have [correction: HAD] on my '50 3/4 ton. If you are changing to a different rear end, are you sure you need the stock U-bolts? The stock 3/4 ton rear end is a huge diameter compared to most rear axles that you would be replacing it with....isn't it?
I changed my 3600 rear end out to a GM rear disc just this year.
