When the 16" Pony's debuted from Ford, I had to have a set for my 86 GT.
Mind you and taking you back in time, it was the first year those rims were available
and only available via a wrecked Mustang OR buying directly from Ford. I paid in excess of $1k for my first complete set of 16" Pony rims... eh... To me, worth every penny back then...
