Spring reatianer time methinks, then some dislocation cones to keep them where i want.
The Mk1 retainer, take a 180mm long peice of 6mm flat, bend both ends to encompass a 150mm spring. Drill center 12mm, use 10mm bolt and washers to secure.



Would like to have a looky at a Landy with something similar, as you can see the spring varies in height from the axle as you move around the coil (well it is a spring) just need to be sure it wont work loose with bouncing. There is enough lateral retention to make sure as long as the flat stays there the spring cant slide out either.
