Gotta be the mounts. Does the gear shift knob move at all also??

I AM STARTING TO LEAN IN THAT DIRECTION . THERE IS A LOT MORE HORIZONTAL PLAY IN RIGHT AXLE THAN IN LEFT AXLE. WHAT ALSO HAS ME CONCERNED IS THE RIGHT REAR WHEEL APPEARS TO SIT FURTHER OUT IN WHEEL WELL THAN LEFT. I AM ASSUMING THAT THIS IS NOT NORMAL

Now it sounds like a wheel bearing. Jack up the car and see how much play when you try to move the wheel 12 to 6. Should be none.

It's not unusual for there to be some mis-match of how the wheels fit in the rear fenders. Pretty common, in fact. But it generally isn't a whole ton of difference, maybe a half inch?

Grab the wheels and wiggle as Geoff suggested. Also try to move the whole trailing arm! Check the CVs. Check to make sure that there isn't anything loose in the trunk. (Don't ask how I know that one.) Check the muffler bracket and its attachments, particularly on the tranny end. Check the rubber engine mounts in the middle of the motor mount bar. (Assumes a 73+ or sideshifter conversion.)

Dave:
I had this same problem bothering me for a long time. Finally figured out it was an alignment issue. My right rear wheel was too close to the tranny and thus the CV axle would clunk on something when I accelerated in first /second. Also noticed that it was easier to replicate when turning right at the same time. (like in a parkade or out of a prking lot onto the street) The CV axle must hit the stub axle or something in the wheel assy. I could replicate the noise by getting under the car, grabbing the axle and pushing it towards the wheel. Clunk! So, I pulled the wheel out a little bit by loosening the outside suspension mounting bolts. Clunk is gone. You can also look up the shock tower from underneath and in my case it was clear that my right shock was closer to the inside of the car than the left side. I have not had a proper alignment done but my homemade "eyeball it" changes at least got rid of the clunk. I also stuck a shim in the outside mounting point to adjust the camber.

You probably should have the alignment checked--at least the rear toe angle!!

well I have tried everthing including adjusting rear track. I am going to stop for a day or two to regain my sanity. I will then start from scratch because I am obviously missing something. Thanks to everyone for your input and ideas.

My 914 did the same thing and it turned out to be the outside trailing arm bolt.
It has to be torqued to 108 lbs.

Now get the alignment checked. "Adjusting the rear track" is actually changing the rear toe angle--a lot!! Toe-out in the rear has been described as "pure evil". The car will want to go sideways on occasion with zero provocation. You want to make sure you've got a little bit of toe-in, and that it's the same on both sides.
