21t servo to 25t servo adapter?

[Glitch]

Hi all!

I have a 21t servo and want to upgrade the servo saver. Not many options out there, but mainly I don't want to purchase a 21t servo saver that I will never have any other need for besides this car.
Is there any kind of adapter (preferably metal, this is a metal gear servo), that could slide on and convert the 21t to a 25t? Seems like a simple enough piece, just can't find any online.

I’ve never seen one, but I just googled ‘servo spline adapter’ and got about a million hits. I’ll let you sort out the responses!

Thanks for the response! I still didn't see anything that would work after looking it up, but it's all good.
