Hello- I am replacing the battery for the first time in my Turbo , which came from Europe. Found a battery locally for a regular 2002, brought it home and its a no go....too long and it does not have the grooves for the hold down on the ends. After doing some research it looks like a 21r is correct but it seems like I will have to special order it. Before I do that, I just wanted to check with the Turbo community and get some advice. Thank you
