1st in my heat. 4th in the main. foot to the floor most of the night. 14in of 1/2in plate for bumper brackets welded to the k frame. 12in of 1/2in plate under firewall on the frame. next investment.... skidd steer tires..
Mine typically bend at the firewall but didn't you say you had some 1/2" plate there? If they don't bend in front of the firewall they will bend in the doors. After all something has to give.....from where your feet sit to the front bumper I can think of about 6 spots on each side that I've had them bend.
I did trim around the rear tires before. And they did give me some issues.
This car bent right in front of my plate under the firewall and split the frame seam. I'm thinking I might have put my plate a little to far back.
I also put my rear hood bolts all the way back where the fender meets the firewall with a 1/4in plate gusset. I think that caused the fender to stay straight but the frame bent. It pushed the tops of my front tires into the inner fender. That gave me some issues. I noticed most of mopar 17 cars the hood bolts are all on the front half of the hood.
I think between those two things that is where I went wrong. I will post pics later.
