M104 Fan Bracket

[glenmore]

I am having just the worst luck with parts lately. The belt tensioner I bought a year ago and now installing turns out to be defective. Looks brand new but grab the flat bushing and you can spin it either way with no tension at all. The shop is selling me a new one for cost, about $50. So I'm checking out all the pulleys and I find I need 1) Idler pulley. Still smooth but spins forever with a high pitch squeal so no grease left at all, 2) New rebuilt smog pump and pulley. The pulley was not so bad but the bearings in the pump were grating, and 3) Fan bracket. The bearing is notchy and grease is leaking out the back of the bearing. So I get the new bracket and put it in while I wait for the new tensioner. There are 7 bolt holes in the bracket. Two are tapped for the idler pulley and the bolt that holds the heater return line. The upper right hole and the 2 in the center are the small holes. The upper left (to secure the smog pump) and the lower right (for the "wet" belt tensioner bolt) are slightly larger. I confirmed this with the old bracket. But in the new bracket the lower right hole is too small for the tensioner bracket bolt!!!! This hole is the same size as the three smaller holes!! Part numbers are the same for both. It seems there was an error in manufacture. Anyone else ever have this problem?
