when i bought my 67 3/4 4wd it had a rochester 4bbl on the 327. i would like to rebuild it but i can not find the id number. most of the time it is written on the drivers side of the carb right? where else might it be?

I think the 4 barrels are on the passenger side.

The quadrajets I have owned were all on the drivers side.

Here are a couple of sites to check out. The first has a pic of where the numbers are:

My quadrajet number is on the driver's side. Also, it is a rochester design that was built by Carter. On the drivers side it is stamped with the words "manufactured for GMC by Carter".
