Excuse me.
Heritage F150's were 2004.
There are no problems with the edge es on which the gryphon is based on.
And
No problems with the gryphon itself.
So if you want a "gryphon" you'll have to do the upgrade option.
Which is.........
Buy a new or used edge es for the 97-03+04H F150's and send it in to get upgraded.
PHP's decision was a business one and one not based on any issues.
JMHO
Peace!
