Not much to do when ur off work from loosing arguement with a van, so got busy...
Put the old springs back in.
moved the link arms to lowest hole on he axels (there is 3)
moved the top of the link arms to top cahssis hole
Results in about 4 inch clearence and better articulation (yes thats flex Gixer, sorry)
Swapped springs
Clearence
Loooks like this free standing
Flex/Articulation (max)
was forced to trim the lower edge of shell as was catching during flex
I think it needs weight, but its lower and low longer too!
Thats great as it did try to go up the stairs but I ran battery down at Ding Dong so its on charge again!
