Upgrading brakes question

Can someone tell me what brake fluid a 2009 Dyna Wide Glide uses? DOT5, DOT4 etc? The reason I ask is, that I am thinking of upgrading the rear brake caliper on my 1986 FXR, (which uses DOT5 brake fluid) to a twin piston caliper from a 2009 Dyna, and wanted to know if there is a compatibility issue with the brake fluid. Because, I believe different brake fluids need different types of rubber in the seals etc. Thanks in advance for any help or advice.
