This kit is composed by 3 parts:
The upper part must be fixed to the body (with glue and/or two screws), the lower part is a crossbar and must be fixed between the chassis rails. Note that my kit is designed to mount an R2 2 Speed in the front, so the chassis rails are 8 mm more distant than the original configuration.
A M4 screw is needed to fix the two parts. The kit includes a washer.
Please contact me if a standard configuration is needed.
