Well, they are miles better than the Tabco panels but some of the KFV panels fit better than others. The floor pans are just about drop in and weld, the other panels all seem to be too big, which is better than too small. At least with the panel being bigger you can cut it up into 2-3 separate pieces so you can make each edge match the way it should then mark it, cut it and then weld it all back into one piece.
Here is the first D/S dog leg I installed, I didn't realize at that time that the panel was too big so I still have to go back and cut the bottom where the marker line is to get rid of that droop.
On the P/S I saved myself that work by cutting the dog leg up and using it as a patch, the marker line is where both panels were cut and welded.
The bottom of the fenders and deck lid supports were the same, I had to cut out as much as a 1/4" in places, then reweld them together. I hope I don't sound like I'm complaining because I'm not, nip/tuck and massaging is all part cutting out rust and putting fresh metal back in.
After I scrape as much paint off as I can with a heat gun, I usually start blocking with 80 grit, but this time I thought I would give these a try, Norton Blaze rapid strip disc. I've tried the 3M version and it wore out so fast it was waste of $. These aren't cheap at $27.00 CDN a piece but I've done a little more than a 1/4 of the car and you can see how little has worn away. I'll probably go through 3 discs for this project and save probably a 100 hrs and a lot of wear and tear on the back. The only down side is they dump everything into the air, even with a fan on sucking the dust out of the shop there is still a layer of leaded red oxide dust on everything.
