the number i mentioned was a complete kit for the wj/tj block into a mj. bought the kit for mine, comes with block brackets/motor mounts and meteric hardware. i got the super flex mounts for mine and there is a noticable vibration, have one more thing to try (think my tcase is mounted low and binding the motor mount bolts causing the vibration) then ill go back to a stock rubber mount because i like a smooth ride. i can't say enough good things about brown dogs customer service, and if your a NAXJA or jeepforum member you get 10% discount
