I have a 460 from a 76 f250 in my 79 and I am currently using v-belts and a saginaw power steering pump with a non AC bracket modified to work with AC. I would like to convert to the multi rib belt setup off of a van so I can use the same pump. I have all the 87 truck part numbers but not the number for the van AC/PS bracket for saginaw. Does anyone have this # and is it compatible with the other truck brackets.
Will the water pump pulley fit my edlebrock water pump?

I have the following numbers for a truck....
Crank Pulley E7TA-6312-AB
Water Pump Pulley E7TA-A8509-AC
Truck AC/PS Bracket E7TA19E708-CA (need correct # for van/saginaw)
Alt/smog pump bracket E7TA-10239-AB
Alt adjustment bracket E7TA-10159-BA
Idler Tensioner Pulley E7TA-6B209-FC

What year did they stop using all these parts/numbers and are they all compatible with the van PS/AC compressor bracket?
