These bodies fit the Tamiya M-Chassis series cars (M01, M02, M03, M04, M05 and M06).
Please check the wheelbase length matches one of the lengths you can set your chassis to before purchase. To check the wheelbase, simply measure wheel nut to wheel nut. Note that M03, M05 and M06 are easily adjusted by adding or removing a part. M01/2/4 are less simple to adjust.
