So on to the convertible floor braces... these were a bit of a PITA! the initial fitment showed that I would be using LOTS of screws to suck them up and get them to contour to the floor.
I used a Trans-Jack to hold the main brace into place so I could mark it off and drill out the holes so I could weld from inside the car. When plug welding, I like to weld to the THICK metal of the floor brace, rather then to the thin metal of the floor.
Epoxy primed the inside of the braces...
Using the Trans-Jack to hold brace in place to mark floor...
Used screws to SUCK the brace up to contour the floor... it actually turned out to look JUST like the original that I still had in the shop for reference.
Used the original floor to take some measurements... but also used some measurements off of the front firewall to make sure braces were squared up with the car.
Here you can see all the screws holding the floor in place... it has some welds already done.
NOTE: make sure you use either the original cross brace or whatever brace you will be using to make sure it will bolt up BEFORE you weld in the left/right rear brace. Here I am using Speedtech's Torque Arm brace to make sure everything is OK before I mark off the location for the left/right rear braces.
Marked off for the left brace... drilled holes to plug weld from the top.
