Im Swapping Out My 12 Bolt For A Sf 14 Bolt In The Rear, I Measured The Distance Between The Spring Perches And It Looks Like The Perches On The 14 Bolt Need To Come In An Inch Or So, My Question Is: Should I Reweld The New Spring Perches So That It Angles My Pinion Upwards? And If So, How Much Should I Angle It Upwards By? Any Help Would Be Much App.
