This is an aluminum rear body mount block made for the Yokomo R12 platform and intended as a direct-scale accessory for 1/12 touring RC cars. Its role is to secure and allow fine adjustment of the rear body shell's mounting point, giving you a stable attachment and predictable reference when tuning rear body height and fitment.
Compatibility is based on the chassis list supplied with the part source. The block is suitable as a standard replacement on YOKOMO R12 and can be used as an option on specified GT-series chassis. Confirm hole spacing and mount alignment on your chassis before fitting.
Installation notes: remove the rear body shell and existing mount hardware, test-fit the block to verify alignment, then tighten mounting screws evenly. Use appropriate hex driver for the existing hex screws and avoid over-torquing to prevent thread damage. The block is intended to work with existing body posts and mount hardware on compatible chassis.
Tuning role: this mount block provides a fixed, repeatable reference for rear body positioning, which helps when comparing different body shells or making incremental changes to rear body height during setup sessions.
