No mods, just tools.
You need a Trilogy pump kit. The 2k and pre-2k kits won't fit the threads on your front block.
ANS has one for $25
has a ton of others.
CCM doesn't seem to have a kit for a Trilogy.
I have a Team Hooptie
pump kit. Works great and isn't too expensive. Plus excellent customer service. I accidentally ordered a Trilogy kit, contacted the guy making them and got a free 2k guide rod in the mail.
They all do what they are built for just some do it nicer than others.
Trilogy pump rod is unique so just make sure it comes with one.
