System I replacement arm - This arm can be used for the system I tremolos. You simply remove the old arm and socket module and replace it with this one. The difference is that your old socket is threaded in and this version is sandwiched in.

To make this work, you simply drill out the 9/32" (7.15mm) arm hole, enlarging it to 3/8" (9.15mm), making the hole larger, so the new arm module will pass thru. (This is very easy to do and requires practically no skill at all.) Then you just clamp it together with the  included 3mm wrench to tighten the arm the the body. This arm looks and feels exactly like the original system I arm did. And when you lose it a new one will always be available.
