Speedo gear info needed

[rod7515]

I need to buy new speedometer gears since I am changing ratios. I have a 904 and was wondering were I can purchase the trans gear for both a 3:91 and a 4:56 gear sets. What vendors have them available?
Thanks Rod

Figure ouy how many teeth you need and put it in the wanted section, seems there are good results. Hey found mine that way!
