Several years ago I bought an OEM power steering gearbox for my 1980 Fj40 and I'm now trying to figure out the heat shield installation. It should be fairly simple. I have four different mounting brackets and it seems that none of the combinations I try work. Hole alignment on the shield to the gear box just dont seem to work out. Is there a difference between manual steering and power steering heat shields? Thinking that I may have a heat shield for non power. Thanks
