I have two 1980's Fuji America. One I bought new and the second used some time ago. This week I rebuilt my original using a set of 105 components and 700 c wheels. The brakes are standard 105 double pivots and they barely make the grade seating on the 700 rim. Could use a longer 57mm reach brakes. The bike originally had 27 inch wheels as I recall.
I did drill out the fork crown to use the recess nut for the 105 front brake. I used another 105 front brake on the rear using the original nuts and washers. I used the 105 STI brakes and shifters. The America came with bar end shifters,
The other bike converted to a credit card tourer with S&S couplers and had the braze-on reworked for the brake bridge, brake cables etc. My son now has it along with his Opus III and S-10-S from the same era.
