I read somewhere that the X20 is a modified version of a challenger model, but Im scared to buy something that wont fit perfectly...
If someone can help me out!
X20, Challenger X and Challenger 2000 have the exact same floor layout. But most that cut custom kits will address the X20.
Here is my install from 8 years ago. It's one of the best investments for that boat. Be sure to get it with the 3m Adhesive backing on it, don't mess with spray glue!
