Here are some pics of the donor vehicle. It was hit from behind, rolled, and rammed into some concrete structure. The miracle, besides the fact that the driver has fully recovered, was how relatively untouched the engine compartment remained.

This is a 2004 F-150 Supercrew with 2369 miles. It has a fully functional 5.4L engine with 300 hp, 365 lb.ft of torque, and is rated at 18 mpg on the freeway. The MSRP for this truck was $35k. I bought the remains for $6k
