My current Dana 30 has 3.07 ratio high pinion reverse cut. I had no idea that not all Dana 30s are configured the same. I was able to find 3.54 ring and pinion through East Coast Gear supply. Derf was right, they are a great company to work with. Doing a little research with a 3.55 rear and 3.54 front there should be no problem as the difference is about 3%.
Thank you all for the help.
