How much would you guys pay for this?

[Boosted1984Silverado]

Thinking about purchasing this truck. This is what I know.

1979 1/2 ton.
Has a knocking stock 454 with Turbo 350.
Paint faded.
Glass all in tact.
Roached tires on steel rims (currently).
Interior fair (see pic).
12 bolt with 3.08s
All the electrical seems to be in order.
Manual locks and windows.
A/C delete.
Wood in bed needs to be replaced.
Some minor rust in a couple places but otherwise all the body is pretty much straight.
Grill is damaged.
Electrical is in working order.

Let me know your thoughts please on a price. I have till Saturday to figure this out. You guys get to help me decide! Please see attached pics. I have a big weakness for this year of stepside, especially with a big block (knocking or not) so I don't want to let my emotions control my wallet. That's why I am seeking second opinions on a realistic price for it.
