Tie rod ends, 70 Mustang spindles on 67
I am having a little problem getting my tie rod ends to seat in the spindle arm. The spindles (with disk brakes) are supposed to be 70 Mustang; I have installed them on my 67 Mustang. Ball joints fit great, but tie rod ends (also 70 Mustang) will not seat deep enough to get a cotter pin in the castle nut. I knew from git-go that 67 tie rod ends are too small for the later spindles; thought all I had to do was get same year tie rod ends as spindle. Any ideas???
