I finally got around to installing my E350 7.3L power steering pump bracket to use the GM ham can and a pump from a '93 E250 with a 4.9L (AZ/Endurance part# 7075). It turns out, the diameter of the shaft is larger than my dual v-belt pulley. I have a pump from a '90 E350 with an IDI arriving today (AZ/Endurance part# 7085). I'm just curious if I'll run into the same problem here, or if I need to just get a different pulley. None of my searches return any info or availability on a PS pump pulley for a v-belt IDI with a sag pump. So to anyone that's done the swap, what pulley did you use?
