Fiberglass isn't clear to begin with and the hood for a merc PU truck would be a very special one if someone can make it up for you meaning $$$$$ at least dude!! Buy the stock ford hood and let that do ya!! Just my 2cents for all its worth to ya!!
Gene Winfield did his own plexi fab for a few rods he built. He mentioned that if you were to take your form (your old hood)and lay the plexi over the top, place it in an oven where it could soften the plexi. The oven could be as simplee as a box with a few 500w quartz lights to provide the heat source.
How do you intend to support the plexi. Even with shape, its pretty flexible. It'll grind your paint away wherever the edge touchs. Holding it down with hood pins?
Fiberglass may be your better solution, but you'd better think how to reinforce it. Otherwise, it may end in your windshield when you hit 60 mph.
I just havent even been able to find any hoods not even on old truck websites, so i was thinking of making one some how, since my hood was used behind a snowmobile its toast and mia. even if i wanted to fix it
Have you been searching for a "Mercury" hood or a "Ford" hood? In the US there was no "Mercury" pickups, that exact same truck was marketed as a "Ford F100" here, there are ZILLLIONS of them and TENS OF ZILLIONS of parts.
My brother is building one at this very time in fact. The hoods are not hard to get and in fact there are fiberglass ones made. I'll try to get you the info on them.
It is a lot more involved than just heating the plastic. It must be mounted in a wood frame and uniformly heated in an oven to precisely 350F. Then quickl placed on the form and cacuum formed on place. The form must be very smooth and free of anything that doesn´t like 350F and very well reinforced since a few ounces of vacuum can translate into many hundreds of pounds of force over a big area like a hood. IF you had a good pattern and IF you could find an outfit withan oven and vacuum table big enough, plan on paying around $1000 IF the first try worked, which it wouldn´t. A bib bunch of the $1000 is inthe initial setup charge so subsequent tries woudl be relatively cheaper but plan of doing 5 before getting a keeper @ about $250-$300 per. In summary you would invest a minimum $2000, not counting the cost of makign a good mold.
