84 audi 4000 S starter motor replacement problem

Hello,

I am replacing the starter motor in my 84 Audi, 4000 S - I cannot get the top bolt on the starter motor to move, it is in a very awkard place, I litterally have about 1" of swing for the socket wrench. The car is up on a ramp, about 8" off the ground so I am on my back putting the socket wrench thur the area where the front wheel axle comes thru. I can't get any leverage on the handle.

Is there a better way to do it (other than taking it to a mechanic...) ?

Any help would be appreciated.

thanks Rush Tucson AZ
