Thank you for viewing. The product is shown in the second photo. This product can be attached to the following chassis if you cut it at the location shown in the third photo: ME, MA, MS, FMA, AR, VZ, S2 Please refer to photos 9 through 15. Please check the fourth photo for the amount of material to be removed. Back sliding is also possible. Please check the fifth photo. When assembling, insert a 1.5mm spacer at the screw tightening points. Please check the sixth photo. This anchor is designed with a theoretical width of 104.7mm. Whether using 13mm or 19mm, it's still 104.7mm. Even if you attach 13mm and 19mm on the left and right, it's still 104.7mm. This pattern is unlikely, but please use it for your setup flexibility. See photos 7 and 8. Since it is made with a 3D printer, there may be slight errors. Please feel free to ask if you have any other questions.
