Boy am I an idiot...I tore my dist apart and got set to twist em out and decided to try the t-20 one more time and with a little persuasion it fit!! Both screws were either very tight or had some edge to them that the driver had to be finessed to get the 20 in there. Once I got it in, they were a bear to get out, but came out without any damage. BTW that T-handle version looks like a much better way to do the job!
Thanks for the replies!!
