Thanks for the reply Jeff.
My detent is completely gone.
No luck at Green Sales, but I will keep checking with them monthly, thank you.
Read on another forum that a 79 detent plate may work if you do a little drilling?
"I recently installed the shift detent plate I pulled from a 79 Ford F250, and all I had to
do was gently file a tiny bit off of the right side of the plate for it to fit into the slot...
I'm talking a tiny bit. Works like a charm."
At this point i'm willing to try it!
