Post Struggling with roll centre height

Hi,

I'm trying to design a double wishbone rear IRS for my 1972 Valiant Charger which was originally a live axle diff car.

Front (almost complete)

Rear

As this is a from coil over car, I decided to see if I can design a rear Coil over IRS with double wishbones.

It is a front engine rear wheel drive car but the roll centre is 35mm above the ground and I'm pretty sure the front is higher..

Wheel base is 105 inches

What am I doing wrong?

Anyone got any ideas?

thanks,

Brett
