Stop in for a cup of coffee

What ratio came out and are going in. Not sure on a 7 1/4 but 8 1/4 magic number is 2.45
Add this up to stuff i didnt know yesterday. Its a 2.26, 2.76 will accept the 4.10.
so i bought the gears and bolted the ring gear on. Basically im on my own. F’ers. Supposed to be knowledgeable people. not all is lost, the barracuda has 2.76,so R&P should work in it.
