thanks larry. those are great pics that is exactly what i'm wondering about. 71 stepside's perches were in the front positions mine were in the rear , both were from v8's. mabey the automatics from 67 on were in the front position or big block v8's. i can't wait to compare the 63 to 66 perch i get to the one i bought of a 67 thru 72 truck that had a v8 to see if they are the same. if all 63 to 66 v8's use the back position and only the 292 uses the pass front position, why is there a front drivers side position on my 63?? mabey it will always be a mystery.
