Outdated Miramar Coupe Body 1.006

• Fixed missing steering wheel
• Reverted partial jbeam to mod version [1.004]

I realize the current version body has these new floor nodes, but can't seem to include them into the mod without them distorting the mesh or exploding. The missing steering wheel is relatively more straight forward so I decided to just do a simple fix instead.

This means most nodes/beams/collision remains the same as mod version 1.004, which still has the door openings sealed by collision triangles.
