Should I buy this?? - 65/66 GMC heavy - Help me decide by 9pm

[GMCMG]

Here's the deal: I don't really have the extra cash laying around (got too many projects already - and one in pieces in the garage). But it seems too good to pass up, and I really need to make a decision tonight, as someone is coming to look at it tomorrow, and I doubt they'll pass... FYI, my wife says no, so I thought I'd put it to a vote on the forum here! Go, democracy!

Here's the breakdown:
Says 65 on windshield, but grille says 66
Clear title
RUNNING 305 V6
4 speed tranny
brake line is leaking, so hydraulic clutch doesn't work right now either (haul it home)
Passenger door - folded at the top - but I have an extra door or two
Cab is pretty straight, but could use a corner and I imagine some floor?
He claims it is heavier than a ton and a half, but I don't know (forgot to get the VIN
Don't know much else about it, but I got the guy down to $450. I probably need to give him an answer by 9ish tonight...
Let's see what everyone has to say!!!
