Where To Place Stands When Replacing Framerails/floor Support

You will need to place the jack stands under the rockers ,everything else will be gone in the front ,make sure you set them back far enough to get the torque boxes in . put them in the rear of the rockers as well . put stands in the very back of the car as well ,not under the rear end, you will need it to stay solid so somewhere under the frame rails . Make sure the car is level side to side and front to back. i would put the front frame rail assemblies in first ,jack stands in the very front and at the back ,again leaving room to get the torque boxes in. I found it easier to assemble the front clip outside the car making sure it is square and level before welding it together ,bolt the lower brace in between the rails ,the one under the motor .This will keep the rails the proper distance apart .you can clamp a piece of angle iron or square tube across the top to keep the top the correct distance apart. I then use one of those lift tables from Harbor Freight to roll the front clip in place and lift it ,they are fairly cheep and believe me it will save you some time and heavy lifting. .Once you get the front clip located screw it to the fire wall that way you can make any adjustments you need to. the torque boxes should be next ,that will keep the front clip solid . after the front clip and torque boxes are welded then do the toe boards and the floor supports ,and finally the floor .

Be careful crawling under the car even when it is on stands ,it is possible to accidentally kick the stands out from under the car .

Yes they will hold up there will be very little weight on any one stand . make sure the stands dont stick up into the floor because of the notch in the top of the stand it may interfere with the floor when it goes in
