Wishbone radius rod bushing (rubber ball))

[blucar]

After many years of being torn down to freshen up the brakes and suspension I have finally gotten around to putting 'Henry' back together.
Putting a new rubber ball on the wishbone has proven to be a very difficult task. I have a new rubber ball which I have had for years, the hole in the ball is much smaller than the metal end of the wishbone.
I need a little help with the installation, of the ball onto the wishbone. All of the vendors tell me that the rubber bushing ball has bee n out of stock for years, so I don't want to screw up the one I have.
