On the TR-6 engine the ring gear and the flywheel are two separate pieces 
which are held together solely with an interference fit. After enough 
starts (100,000 miles maybe?) the cumulative force of the starter pinion 
hitting the ring gear will push the ring gear back far enough to make 
engagement difficult or impossible. Shimming the starter will make the 
problem worse, and replacing the starter motor may help for a little while 
but not for long.

  You could try one of the new gear reduction starters (try TSI or BPNW) 
and see if the starter pinion moves out farther than the Lucas design or 
you could mill the face of the starter motor so that it sticks further into 
the bellhousing. The best solution is take the flywheel off and push the 
ring gear back into position
