Picking up an old Bracket car. Have some questions

I have another question. There was a modification to the body that I would not have done because it is a uniform car. The inner fenders have been completely removed. It has not had any ill effects on the last 40 years of racing. I have always heard this was a big no no. Would you worry about it, reinstall replacement panels or install tubing between the firewall and core support. Maybe tie it in to a full cage at some point.

I look forward to your responces
