Either will work. ( I get the 2 confused)
One (the Universal (I think) has an "L" attachment leg. (If installed as we did, the foot of the L has to be removed)
The Other (Yamaha (I think) has a straight "I" attachment leg that works as it is...
I just installed the Straight Legged Model (Yamaha (I think) on a C-1400.
Cheap,,, Little more difficult to do, but it Works great!!!
Ride safe, Ted
