Thanks to all for your recommendation and advice. I actually bought the tools rec'd by @KZJonny and set out to move my car closer to the house to begin bumper removal when the car wouldn't start. Jumped the battery, had the car running, hood up, a neighbor kid/young man drove past and asked if he could help. I gave him the litany of what I had to do, junk yard Montreal, bumper, yada yada. He offered to help. Next thing I know he's using Axe body spray and a lighter to even out the dent in the front bumper. Using zip ties to hold parts of my bumper together, and just re-clipping the rest into place. He took the whole thing off to inspect things. Tried removing one bolt that never budged, but then assembled everything together looking tight and smooth.
I think my GT would have been sitting in my driveway for years (mechanics too busy anyway with the aftermath of the big storm in Quebec in May - still cleaning that up - to take on my puny job. Even though they quoted me a huge fee) - if I had not come to this forum and got chatting with youse all about possibly doing this myself. Which drew the attention of my neighbor.
Note: I hate doing this kind of work. I'm much more at ease with software than hardware.
Some photos for your amusement.
Now onto fretting about other work needing to be done....
Cheers to all,
Beatty
