Carburetors? any info would be great!

Hello all, I've got a few questions regarding the carbs that were installed on our trucks. Maybe there is a thread out there that explains a lot of this.

I see that Rodchester, Carter, were pretty common. Qudrajet 4BB and Dualjet 2BB? What sizes were offered and which intake would mate the sized carb? or were the intakes all the same just the carb

When looking to buy a used carb what are some tips to make sure your not buying junk. I heard that a lot of these carbs get locked up due the the leaded fuel attracting water then rusted shut. A lot of used carbs out there are missing linkage is that something to stay away from?

Are there any manuals on the various carbs to tune or rebuild?

I know i have many questions but these old carbs spark an interest and would like to know more about them.

Thank you
