I decided to work on the front suspension since I was tinkering with the sub-frame. I installed a C4 Corvette fiberglass monoleaf set up on the real car. So to add it to the model I made a brass insert for the cross-member where the spring will be mounted.
The upper control arms and spindles are the factory GM units, but the lower control arms are special made items. I made this pair from sheet styrene.
