i think this may be affecting my 60ft. times. im not sure if its right but i did notice a few weeks ago that there was more space between the front edge of my right rear tire and the quarter panel....about 3/4" more...than my left. i moved it up to close the gap and noticed a slight improvement in my 60ft. times. my question is, what is the correct process in aligning the rear? do you measure from points on the frame or do you measure from a point at the center of the frame towards the front or do you measure between the center of the front wheels straight back to the center of the rear wheels? i know there are dowel pins that come on the factory pieces that make this easier, but i have landrum drag springs out back and lakewood traction bars...there is an inch of play. also the pinion shims dont allow the spring dowels to fully rest inside the mounting plate on the traction bar. ALSO noticed that any traction bar adjustment (with the snubber gap) doesnt affect which way the rear swings on launching. the back end always kicks to the right, whether on the street or in the burnout box. shouldnt the car stay straight, is this a place im losing some 60ft time?------------------

Good alignment (front and rear) is huge for the whole distance. Measuring corner to corner will get it square if the fronts are in the right place. I like to have the whole car lined up by a good shop with one of them light beam racks. Once it's all in place you might want to make some changes to keep it from moving, u bolts alone will walk.------------------
If you had a rubber cam would it get wilder as the RPMs go up?

its common that the leaf spring center pins aren't the right size for the hole in the axle housing perch, allowing it to walk forward. You can bush these holes down by welding in a washer, or use a leaf spring bolt with a bigger headTom

You have to be carefull using body work as a reference for suspension / alignment adjustments. That car has probably gone thru a lot since 1967 - body men weld panels on to get lines straight - may not be as concerned with wheel openings. Also tolerances may vary on aftermarket parts.Doc is right on the money - get the car checked by a good shop with decent equipment - now where do you find a good shop? ------------------

was hoping you wouldnt say take it to a shop. i been screwed many times on wheel alingments, so finding a reputable guy will be a start. the other is money....just in a tight spot this month thats all. will try to measure "x" off the matching holes on the front of the chasis again, get somebody to hold the tape measure for me this time...see if its close till then. im sure the car has been wrecked more than once, so im not 100% sure about using the tape measure but for now it will have to do.------------------

A Ford shop manual should have the specs in the chassis volume.------------------
