I suggest that you buy the preformed floor pans. When shopping for the pans compare the descriptions for things like metal gauge.
I have made my own floor pan patches for my El Camino and would not do it again. I was never completely happy with the way they looked when I finished but kept...
There is another vehicle that I allowed to slip through my hands. I once had a 1984 K5 4X4 Blazer that I swapped the 305ci for a built up 350ci. I changed the gears to 373 from 308. I only got $1700 when I traded for a new 1998 K2500HD. It was in great condition too.
I took the spouse to a wedding shower in Des Moines yesterday and had some unsupervised shopping. The Dewalt came from Acme tools and the other pile from Harbor Freight. Hopefully the Harbor Freight pile from China wasn’t a waste of money.
