Possible Purchase..how much is it worth?

[454c20]

Hey guys. I'm on the hunt for another project and stumbled upon a truck local. Its a 1965 Chevy 1/2 ton, inline 6 and 3 speed manual. Manual brakes and steering, looks pretty basic. Shortbed too. The truck is from Florida and has very little rust. Owner says the tailgate, fenders, and hood have rust. Underside, cab corners, body mounts, rockers, bed, and floors are solid. The body has been soda blasted and shot with DP black primer. Overall it looks straight, interior looks decent. Runs and drives. What do you guys think its worth? He is asking $5800, a bit more then I want to spend but it has very little rust.

Also, quick question, what rear end choices came in these? I'm sure its stock but havent heard back from the seller about it.

Also, are these trucks really light? I checked some figures and it shows they only weighed 3200-3300lbs, is this right?

Truck will get either a mild 355 or a warmed over 454.

Thanks guys
Nick
