I was just about to put the Toploader on when I stumbled into thread about T5/Toploader speedogears. I have T10 but a friend lent his Toploader (he went to T5) while I attempt "fixing" T10. Now what should I do? Assuming T10 and Toploader have opposite direction speedo gears (whatever that means), I can't use the speedo if I am using Toploader? This should be easy, what I have to replace to use Toploader and speedo?
