Pullrod Suspension

[bretton]

Hello all lm having problems setting up the front suspension on the 644 formula ford and was wondering if any of you's would care to help .The car is running ACB10s and 550lb front and 450lb rear springs and lm aiming for about 50mm ride height as rear uprights are very close to tarmac.
Basically do l slacken the springs so as l can move shocker to enable the pull rod bell crank too meet up with top wishbone and then set ride height or am l doing it all wrong...........
