Alternative to 'Find' in BusyBox

[coaster]

Hi, I'm trying to run a cron job that deletes webcam images uploaded to the USB storage after 4 days. I've used a command on DD-WRT and Ubuntu that has worked:

0 0 * * * * find /tmp/dev/sda1/camera *.jpg -type f -mtime +4 -exec rm {} \;

but it looks like the BusyBox version of 'Find' on Gargoyle does not have the '-mtime' argument. Can anyone suggest an alternative? Thanks

Gargoyle 1.8.1 TL-WDR3600
