thanks all. as I mentioned, this is a science experiment for me. I purposely went routes that required some design, a new skill, etc. I have lots of pictures and will post them here as time goes on. They might be out of order, but I am sure there are people like me who just on the internet trying to see pictures of things others have done to try and understand how it is done or how it can be done.
In regards to stiffening the chassis; I picked up the US Tool sub frame connectors at a swap meet and modified them some, then fully welded them in. I saw the bracing that XV was using and replicated much of that. I did contemplate a cage, but decided against it because I couldn't decide where/what I wanted it to be like. It isn't off the table but I really don't want to hack holes through my dash.
this car is an oddity in that I am going for a lot of OEM look while having a lot of AAR or road race effects (cake and eat it scenario).
