Is this car worth the money, opinions

I guess I need to clarify...
Not a second set of springs, but spring perches. He said the rear end had been swapped out of an "old coupe", so maybe it was thrown into something else? How much wider is B or E body 8.75 then A body?
It does not have any frame rust, I crawled around under it. There is some in the floors, not terrible, but considering it sat with back window open (worthless tarp strewn over it), it should be worse. Between drivetrain, brakes, etc, it is probably worth the price. I am probably a bit leery as there is no cluster, heater controls or HVAC in the dash, plus no door panels or carpet make it look worse then it is.

My thought process is this:
Shoot for 750 or so, to afford the back glass. Give it a safety work over, with brakes, and shocks, carb rebuild and tune up, etc. Reinstall some mufflers, and tail pipes, so it is not obnoxious. Splurge would be some cast "drag lite" wheels with fresh tires. New shoes make everything look better, and it would still be a little rat rod-ish, but at least it would look intentional, and progressing.
