looking to buy '60 fleetside

[lime_rocket]

i have an opportunity to buy a 1960 chevy long box fleetside. from conversations with the seller here is what know i about it:
-running 292/3 on the tree
-good glass
-decent interior
-rust on floorboards, rockers, front fenders and possibly cab corners
-straight frame, very few dents on the ttruck
the asking price is 800$ canadian with a set of eagle alloys on rubber

im looking for a truck to be a low budget restoration/daily driver
what are some keys points to look for when i go to look it over, i.e. things that could rust or wear out that are a huge burden and expense to repair or replace.

thanks for any input.

Ben
