Alright, I have the physical block and door pretty much designed. I kept it as simple as possible. Its still a bit rough (yes I know the control arm in the 2nd pic isn't attached), but I'll tweak it as it's built. I just wanted a rough idea of how long the L shaped arm needs to be.
The block will be quite easy to mount behind the lower grill on the Matrix. There is plenty of room down there. I'm planning on making it out of coroplast. If reinforcement is needed I'll do that with some .030 aluminum sheet I have.
Anyway, pics!
