Moving the rear mount back to adjust the angle of the shackle will also give the kingpin more angle. Likely if it isn't moved back to around 90 degrees the engine weight will result in the shackle flipping over anyway. So moving it will increase kingpin angle again, and prevent it from flipping over.

for the shackle to flip over it would need to go forward ( i mounted shackles at rear )
a good 60 degrees. putting more weight on will move it even further rearward, maybe
even hitting frame. i need to make springs "stiffer" not neccessarily taller, so that they
dont flatten out-thus elongating and moving shackle rearward- as much.

Shackles don't need to be mounted forward to flip over. Once a shackle's spring end gets past 90 degrees to it's mounted end it can flip over that pivot point, and will indeed hit the frame. The next bump may be harsh enough to make the body rise, and pull it back. But it can indeed flip over regardless.

ah, i see what you mean--if it went so far as to "line up" the shackle with the
spring, it could indeed go over center and get stuck. lucky me, in this case
it would need to smash through 3"+ of frame to get to that point.

got it roughed in enough to put it back on the ground.
glad its just tacked for now, as it went from 10 degrees
static + caster, and just the weight of car without motor
moved shackle back from 90 degrees to 45 degress,
and caster from +10 to +8.

i may need to add a leaf or two in the front leaf packs
once motor & trans are in....

That looks so cool. Can’t wait to see the motor In there.
