As far as the jack instruction decal is concerned the procedure on the assembly line goes something like this.... line worker stood on the driver's side of the vehicle, with the decal in their right hand he or she ( political correctness) would just slap the decal on the underside of the trunk...
If you go with the stick on method and discover that the location is wrong you can always move em. I agree with having a hard time drilling holes in nicely finished panels, breeding ground for corrosion to start. Just my thoughts.
Good luck with your car.
I believe somewhere in the fuel supply line you should find a rubber section (fuel filter). I just pinch it off with needle nose style vise grip. Run engine till it runs out of fuel. Or remove fuel line, block off with bolt and clamp ? Repeat procedure. Run till empty. Just my two cents.
Try Jeff at 721 restoration. Got one from him maybe 4 years ago. Reasonable price. Crazy thing was they're manufactured in Quebec (spector ?) and he's in Colorado (I think).
Is the one sister who learned to drive stick on a 426 wedge powered B body single and available ?? If so please send picture of said B body.
