got a few questions on a truck im lookin at!!!

[restorationboy14]

Alright, I have a 69 GMC and would like to add to my collection, Im looking at buying a 60-66 Chevy c-10 2 wd 3 on the tree. I climbed in and it smelled like mice, no biggy. But I pushed on the clutch and it had GOOD PRESSURE!!! it was last liscensed in '02. The brakes are a different story, I pushed and had little resistance, then just was completely free of pressure, Could I have pushed all the junk in the master cylinder into the lines? or was the brake piston just alittle seized up? The wood bed is in AMAZING STOCK CONDITION!!! So my main question is. Is this worth 400 bucks? And how difficult are the brakes on this truck? But my question at the top of my list is this, What is wrong with the brakes???????? it has a I 6 in and looks like a 250. is that correct?? Im very excited about this truck. Thus the reason for all my run on ??????? marks haha. Thanks guys!!!!!!
