straight through 1" clutches

Even if buck$ were not an issue...#160151 is outboard mounting only clutch.
Depending on how engines are mounted to frame, outboard clutches (in my setup) will not fit. #160153 is fine except that I use #35 chain exclusively.
For chains to clear my frame, clutches had to be mounted inboard.
Depends on what works for you.
My Azuza frame had to be slightly modified to accept twin L-B's and took several trial and error attempts to get it right. Symmetry is a major factor.

Just to clarify, an outboard clutch has the sprocket away from the engine whereas inboard has the sprocket next to the engine, right?

If thats correct, then I thought your clutches were outboard on the Azusa/L-B Twin Terror?

Mine are inboard.
