5 speed from a 720

Hi all! I'm finally getting back to my motor swap and I picked up a 5 speed. It looked like the close ratio I was looking for (same case), but the ratios are wonky, so that sent me on a deep dive and discovered it is likely from a 720 with a 240 bell housing. The ratios are as follows:

1st - 3.592;1

2nd - 2.246;1

3rd - 1.415;1

4th - 1.000;1

5th - .813;1

My question is this; Anyone know of a source for the gearsets I would need to convert it to a true close-ratio? I am keeping my eyes open for a close-ratio, but they aren't as easy to find as they once were! I wish I had just bought one many years ago when they were more available!

Thanks for any leads you guys might provide!
