you only use the one truck bracket cause of the spacing on the k-frame and its not in the same spot as a v-8

the driver side would be the bracket they used on a v-8 k-frame before the spool types

it will use the same rubber bisket mount as the truck and early v-8s

driver side is close to block and pass side is got a good size gap the truck mount takes up the space

bolts right in

wont work if its a spool type /6 though
