Good morning, I recently received a part from Ford, it's a rear control arm bolt part (#E9SZ-5K751-A) - BOLT - 135685, it's the bolt you need set toe-in and toe-out on rear control arm. They sold me the bolt for $31.00 but the nut that secures it is DISCONTINUED. I have a useless part for $31.00 without that nut. In order for my alignment to stay correct I desperately need that nut, they may be a washer also I'm not sure. I,ve tried everywhere to find this nut, looks like it's 14mm in size. Please help, Steve. 94 T-Bird 4.6.
