Where can I find a 7.5" trac-loc type kit?

Be Ford specific too.

I got one in an 86 TC but it would cost too much to ship it to ya.
You've got good junkyards up there anyway in Kelowna.
 
Yes, Rangers had this factory "option" and maybe early Aerostar's, but later they went with 8.8" didn't they

You should be able to get one close to home
