No other issues the car is pretty clean...unless that was there from the factory where the floorpan is but i doubt it. When i do a brakestand you can actually see the frame twist a bit and the passenger front side raise up slightly. I do have a 3800 stall and 3.91 gears with a built up tranny, maybe thats why? I dont think its necessary to cut the rear floor pans. The frame connectors came with the car when i bought it they were just not installed, i suspect they are 12 years old but they are designed to weld just under the floor pan and only to the frame connectors. Perhaps the geometry of having it cut right through the floor pans might be marginally better for rigidity but unless im building a drag car i dont think it matters...anything will help me at this point. In contemplating taking the car in to get them welded since i have to run a generator to get the welder going, i also dont have a lift i would need to build blocks. Not that its a hard weld its been at least 5 years since i welded last.
