where should i put the resistors in this ttl clock schematic??

The only place I see the need of resistors, is in series with the 7-seg LED's. These are the ones you are talking about? If so, the place to put them is after each output of the 7447.
Also a good idea is to put a pull-up resistor between ground and the reset input of the 7432's, as if you leave it hanging you can't tell for sure if it will stay to 0 or be raised to 1 by internal voltages, leading to unexpected behaviour. A 5k resistor will do the job I think. But if it doesn's experiment between 1k and 10k.
