OK, I have a week off work the first week of July. I have been planning on using that week to replace the floorpans in my Z.
I have a complete floorpan cut out of another daytona that is 99% rust free with solid rockers and all. My tona is rusted out on both rockers and from the driver's feet back to the rear seat. The exhaust tunnel is about all that will stay. Frame rails are not rusted.
Now, I have noticed that the fit of the doors isn't quite right so I assume the car is actually sagging a bit. Being a T-top car without solid floors, I know there is a lot of flex.
My plan is to level the car up on stands, strip the interior, cut the old floor out and weld in the new. What I am wondering is how I will go about making sure the car is straight before welding in the new pans. I imagine once I get it up on stands I can weld in some bracing from the front door jambs to the rear about half way up and then a cross across from the drivers to the passengers side. This would just be temporary bracing until the pans are replaced.
While I have the pans out, would there be any benefit from installing some subframe connectors? Something that attaches the front frame rails to where the rear axle arms attach to the body.
I am already stocked up on .024 wire for the welder, a full tank of steel mix, some extra 20-gauge sheet just in case, and all the pneumatic tools you could dream of.
I've replaced quarter panels on other cars in the past, but never this much floorboard. Any and all advice welcome. My main concern is welding it all up and finding out the whole car is tweaked somehow.
