I'm looking to install new carpet on my 2004 Triton TR-20x bassmaster classic edition and i see there are pre-cut carpet kits for sale on the web. I can't find one for the TR-20x specifically but i do see kits for the TR-20 and TR-21x. Is the TR-20 the same as the 20x deck dimension wise? Or Should i get the 21x kit and cut it down to the 20x size? Trying to figure out best option here.
