I changed from drum to disc also installed new lower control arms. I intend to take her to a shop for proper alignment but would like to try it myself first. It will be nice to know how close I get! Question is how and where to start, I ran across a site awhile back that had good info. but can't find it  Any help would be great! Thanks Pete

Pete, I want to do the same so I will watch the responses. I don't know if you have the tools to adjust the camber, etc, but any 67 shop manual will have the statistics. I would be happy to send an attachment with the stats from a 68 manual if you need them. You could email me @ [email protected].

You may not like my answer, but I would leave this to a Pro  When I had my TCP strut rod installed few weeks ago, I had a long talk with the guy that did my alignement: It is a very complicated operation since Caster-Camber and Toe-in adjustements are interdependent. There is a special sequence to respect. Angles are highly sensitive: 1/8" change of position of strut rods or lower arm and you are way off on angles.
The only thing I did was to approximatly adjust caster by using a thread in a needdle (I wanted caster not too far off since if caster is wrong your steering will act very funny). I will try to explain: There is a hole in the center of the upper and lower ball joint stud. I positionned the thread in the hole of the upper ball joint and let the needdle hang down over the lower ball joint stud. For caster to be correct, the needle needs to point between 1/8"-1/4" off that center toward the rear of the car. For the rest (Camber and toe-in) I did by eye estimation
and off to the shop I went !!!

Oh !..... This must be done with the car on the ground
BTW: when I got there, caster was not too bad !!!!! I was +1?43 on the right and + 0,75? on the left

Thanks Ralph I didn't think of that, I have a 67 shop manual. She is in getting exaust right now and my manual is there I'll look when she gets back!! I'm pretty sure the disc brake setup came from a 68 coup my car came with most parts in boxes. I got extra parts from 3 different 67/68's. I paid 1,000 for the car and parts http://67fastback2-2.mustangsandmore.ws
Pierre, I will be trying your method out sounds good to me Thanks Pete

i had my sister hold a piece of yarn across the middle of my rear tires, while held it acoss the middle of the front tires, you can see the gap in the front tire to the string, so you will know wich way to ajust the wheel, in or out with the tie rod sleeve,
also make sure your wheel is some what in the middle, its not to big a deal to have the wheel perfect seeing as how once you get it to the alignment shop they will fix it anyways------------------

I'd say, get your toe close and drive it to the shop. You won't get it right anyway, and close enough is just as good as far off when it's on the alignment rack. I wouldn't suspect that the '67 is far from my Maverick, and it is quite easy to align on the machine. I've done quite a few alignments at the Ford dealer I work for. They aren't complicated at all, but without the measuring equipment, nearly impossible. ------------------

I wonder how things have really changed. Forty years ago, before computers, I used to help my Dad align our car at home with string and stuff. I don't know how good a job we really did, but when I get a computerised alignment these days, it strikes me that the whole procedure is still as simple as it was - just a lot quicker, and presumably more accurate. But does it need to be THAT accurate? The world got by fine on string for 80 years of motoring ...
