Work has begun on the rear suspension, I have done my research and I think I have figured out how to do it but there will be some changes made as I go.
It starts with making a welding jig for the rear suspension cradle. The idea is to locate all the suspension arm pivot points in space including the position of the rear diff.
I am using these bits of tube to locate the pivot points which have been cut such that they will slide into a piece of 50 x 2.5mm square box (SHS). The box sections will be cut to create brackets for the rod ends on each control arm. The rest of the frame will be CDS tube.
I hope to build most of it on the bench but at some point it will need to be placed in the rear of the car as it will not be bolt-in to save some more weight. I will use the original 4 bolt points to locate the tube frame in the correct position, however, I will raise it up about 80mm using spacers so the the car is lowered by this amount without affecting the suspension geometry.
