This
adjustment block replaces the fixed central mounting of the spring leaves on an
original front axle and is welded in between instead.
This allows
for infinite height adjustment, also known as 'Sway-a-Way' style.
For proper
fitting you need 2, one at the top and one at the bottom, and good welding
skills are definitely required.
Supplied by
the piece and available for both the early 'bundboltzen' and the later
balljoint axle
