New Motor, A/C comp. don't fit

[85/Silverado]

My new motors valve covers won't let my A/C compressor fit back on the drivers side mount. The old covers won't fit back on with the oversize rockers.
Does anyone know which March serpentine setup will fit the 85 Silverado small block with the long water pump? I want the whole set-up with Chrome A/C unit, Power Steering Pump, Alternator, and the Fan Blades will still fit.?

I know it's over 2 grand but I'm tired of getting screwed around by everyone that works on my Truck.

Or some bracket that will allow me to hook up the old A/C unit to a different spot?

Thanks Guys
Jack
