As parts of Mitch's Auto Parts quest to make the K20 or K24 swap better in your MR2 Spyder, we are selling the new rear mount seprate for though's who may have already purchased the Innovative set but do not like the rear mount design. This mount is from our first production, while these were not perfect they are still usable with modification. The OEM Toyota rear mount that you will re-use will require 1/8" to 1/16" to be filed off the end of the metal through tube to work with this mount. This will eliminate the need for the very larger rear innovative mount. You will need to use the rear Toyota mount that came with your 1zz that hangs from the sub-frame. Bolts are not included.
