They were never meant to go that fast. Even with a brand new front end in it, the design of it is not conducive with higher speeds. Mine has new kingpins all new tie rods, rebuilt and adjusted steering box. Took my and my pal 2 days dicken around to set it up. Each measurement you take or adjust depends on the accuracy of the last adjustment. Probably why hot rodders don’t use them. No he’s right 30 mph is fast enough
