RE spring over leaf?
That good be the case Joopin, maybe they are a fail safe. You can buy the yoke conversion kits, or on the rear axle you can just drill out the holes with a 9/16" bit, buy the ubolt kit from NAPA which runs about 4 dollars, and set it up. It is rock solid. Wheeled it very hard and not had any problems, and when I had the strap and bolt I was busting u joints left and right. Depending on your front axle, (cant remember if u have a d30 or 44) a yoke conversion must be purchased for the d30. Some people claim the drilling method is a bad idea, but I have seen numerous rigs running that way and all have loved it. In my opinion it is very worth the 20 minutes and 10 bucks. If you use the drill method, get a cobalt drill bit, that yoke will eat up a regular bit in no time.
