Howdy,
What are the torque specs for a '68 Coupe front suspension? I don't have a manual and am reassembling the front end today and tomorrow. I need the specs for: upper control arm shafts to the shock tower, sway bar end links, lower control arm to frame, strut rod to lower control arm, and upper and lower ball joints.
A side note: I purchased Mexican made, upper control arm shaft and bushing kits from "Mustangs Unlimited". They took forever to get here, after they forgot to ship them with a couple of other things that I ordered. When they got here they seemed to be junk, but I used them anyway. The bushings had coarse outer threads instead of the fine threads that were in the control arms (I horsed them in making new threads  but they seem OK). Are all of the after market units like this, or do some years have coarse threads and others fine? One more question. I replaced the lower shaft bushings with poly and it got me to wondering, what keeps the lower shaft from sliding or moving frontwards and backwards on the shaft bushing. There is a shoulder on one side of the bushing but none on the other side with about 1/4" to 3/8" of the bushing sticking out of the side opposite the shoulder. Considering how easily the bushing slipped in, makes me imagine that the shaft could, under certain conditions, chuck forward and back that 1/4" to 3/8". Is this just one of the flaws in suspension design, or am I misunderstanding something and shouldn't worry about it? 
Please excuse the L-O-N-G post and thank you for any and all comments.

Gene,I don't have the torque specs, but meanwhile use a 1/2 drive ratchet and give them about 2 grunts. The upper arms will be retorqued when it's aligned anyway. Good luck, SteveW

There should not be any play in that lower control arm. My lower control arms fill the entire frame braket and do not slide forward or back. You will probably want to go out to the hardware store and pick up some washers to shim the control arm in the center. Buy the thinnest ones you can find so you can get as close as possible to center as you can. This way your strut rod wont push the arm forward or back, which may cause binding during suspension travel. Make sure that the arm is as close to perpendicular to the frame as possible once everything is hooked up, then let the alignment shop do the rest.
