Sell as is, or primp a bit?

[HarrisonTX]

So I have this '86 k-5
It's got a fresh Edelbrock performer 350, & fresh front and rear axels (stock 10-bolts). I put on a new "truck avenger carb".

The guy I bought it from handed me a stack of receipts totaling $6,000 (labor killed him). I don't drive it, and I'd like to fund 2 project cars I'm working on.
The drivetrain is solid, but the body has quite a few miles, and the interior is worn. Got a few problems like a cracked dash bezel, and **** carpet, and no radio, slow power windows.

My question is this. Should I sell it as is, or do a couple appearance things and sell it.

I really hate that "roof rack" luggage rack. I have a solid side glass top that I've considered getting rhino-lined.
I figure it would look good with some 33's, a 2 inch lift, a black top, and black rally wheels. That would total maybe $1,000?

I think as is i'd price it at around $2,250, or maybe $4,000 if I throw some cash at it.

Opinions guys?
