I noticed that my bonnet bushing was broken so I replaced it with a spare I have on hand. I hear a nasty vibration coming from my hood and to deduced it was a loose bonnet bushing as it is wiggling in the bulkhead bushing holder. I checked its size and the diameter is smaller than the broken one it replaced and smaller than the opposite side. Are there multiple sizes/diameters of these bushes? I ordered #346849. All my spares are very loose in my 1991 110...
I have run into these sort of differences all the time.
Motor mounts can vary as much as an inch, especially on an aftermarket chassis.
Your other option would be to make a metal sleeve with a slot in it to shim the plastic bushing.
The sleeve would have the same opening for the hood hinge with am OD matching your over sized hood mount and an ID that the plastic bushing fits into with clearance to slide for opening and closing the hood.
