Nice- Same happened to me last Fall. The lady pulled into my on the left side front corner- got the header panel, headlight, wheel, hub, and fender molding of my truck (It was still mechanically fine). After about 6-7 weeks I finally got a check for about $2,600 for repairs. They agreed with the estimates I'd gotten, but they cut about $300 for 'age' or some crap like that. I wasn't too butt hurt over it- I actually had the parts in the barn to fix it (even same color) but best of all- I'd just bought the truck for $3,500 a month earlier. Now I'm sitting in it for less than $1K! Since it's still drivable, I HIGHLY recommend you sink that dough into finishing the F100!! LOL
Working on old cars teaches us patience... and every curse word imaginable!
