Looking to buy a burb need advice

[sgaylord]

I have a 70 c-10 and a 56 3100. I know a little about buying those now thanks to some trial an error. Most of the error came at a price..... Anyway, what kind of things should I look for. I have my eye on a 69. Do the burbs rust mostly in the same areas as the c-10's (Floors, floor supports, cab corners, wheel wells, etc)? Are there any things perticular to the burb that I need to look out for?

Thanks,
Steve
