Rob,NAPA for the hoses but there is a difference from A/C and non A/C.As far as the power top switch goes,they hide it in plain site.Located to the left of the lighter and it looks just like the rest of the knobs.It turns left and right not up and down.Battery cables i would check with Fusick Oldsmobile Products.www.fusick.com they carry them for Cutlass with a 330 and 65 442's with a 400. tom
