Denny,
My recent experiences have been with '54 clips/assemblies (two, last summer), and I do not know if the 47-53 imposes additional considerations.
1-2 bolts for the radiator core support (depending on the support).
8 for the fender braces (I'd get the braces all the way off).
6 for the inner fenders to the firewall.
8 for fenders to the cowl.
Flip a coin about removing the radiator from the core support (6 more bolts? Makes the assembly lighter).
Flip a coin about removing the front bumper (and skirt/apron/shield). If you are going to remove this, I'd remove the 4 bolts holding this "unit" to the frame (keeps you from bumping into the bumper brackets).
Two people can easily take off the assembly and carry it away. It helps to have three people when putting it back on.
