7.25" Gear change HELP

Didn't have any luck with that link. All I could find was 4.10 sets for a 7.25. Sounds like too much. I have my rear diff cover off now and will be checking for any issues and hopefully be able to confirm what is in my 63 GT. I'm assuming original gears were 2.76. If all looks good, I plan to just seal it back up for now.
