Rear End Alignment on 70 911T

I just got back from the alignment shop. First of all, the place I took it has NO experience with Porsche (but what do you expect from a town of 2500). The front end tuned in ok and the back camber was ok, but rear toe in could get no better than -0.48" on the left and -0.39" on the right. As I understand, a negative toe in means the wheels are toeing out, right? Any suggestions on what I need to do to fix this problem?

I keep answering my own questions. Turned out the car must have hit something hard on the left rear wheel sometime during it's life. The trailing arms are ok, but the torsion tube has a bend in it (offset about 1/2 inch forward at the middle). Oh well, off to the frame shop.

....don't give up, this is all a tremendous learning experience, and it helps to have company, doesn't it?

An interesting experience. Took the car to a local frame shop. As the guy tapped the sheet construction, "no sweat" he says. "Hafta be careful not to over do it" he says. "After all, this frame rack's made for Ford trucks" he says. This, quite frankly, did not give me a lot of confidence.

We took off the throttle linkage and bell crank mounted on the transmission, and disconnected the fuel line. He was then able to get a canvas strap in back of the tube on the left side just to the right of the transmission mount. This is the side I think took the original hit. We mounted the rack chains around the shock mounts on the rear control arms. Finally, put a 4 ton jack between the shock mounts to keep presure off the torsion tube.

After considerable tugging, pulling and tapping, with the frame guy scratching his head more than once, the tube finally started moving at 4000lbs of pull plus what ever the 4 ton jack was adding.

After about 4 or 5 pulls, we were able to get about 90% of the bend out. I think the frame guy was amazed at the strength of construction of the 911. In all, the center of the tube moved back towards the rear of the car by less than an inch. By the time the car got off the frame rack, the rear wheels were pigeon toed.

When we put the car onto the alignment rack, the rear wheels literally dialed in at something like 8 seconds of toe out and -1 degree camber, with the adjusters about mid range.

All in all, a successful exercise, but not one I particularly want to repeat.
