Tin Man's transmission cross members for the 1964-1972 GM A Body utilize all the factory mount holes and will virtually install any GM transmission into your A Body Chassis. They also require no modification to the transmission tunnel for a simple installation on 700R4, 4L60E and 4L65E transmissions while positioning the engine and transmission for correct driveline angles and best exhaust and firewall/radiator clearance. TKO,T56, 4L80, 6L90, 8L90 will require tunnel modification to maintain correct drive line angles. Incorrect drive line angles can cause premature wear as well as drive line noise and possible catastrophic failure. Tin Man trans tunnel panel PN #100311 will make this much easier while maintaining the factory console.
Depending on your needs, you are able to purchase engine mounts and transmission crossmember separately or as a kit! Note the difference between the Coupe/Sedan and Convertible.
