Hey man, after about 4 hours of fiddling with it I found the bushing thing you were talking about. Actually it talks about the inner workings of the starter in the TSRM so what I would up doing was prying back the brush springs, pulling out the brushes, and then pushing it down over the lip and re-inserting them. To my suprise when I got it all back together the car instantly started up, I thought for sure that I broke the motor somehow with all my screwing around. Quite the robust piece of equipment they built there.
Also I devised some new ways to get to the starter housing bolts (that bolt it to the bellhousing) since I did my clutch (this is my 2nd trip to hell to take off that starter).
Have a 14mm open ended, 14mm 1/4 drive socket, 10 inch, and 6 inch extentions.
for the top one use all the extensions mentioned and stick them in above all the tubing and what not below the intake manifold and with a little elbow grease you'll get that pesky bolt and be able to crank on it pretty good. While your removing it, for me at least, I had to hold the nut on with a 14mm closed end wrench. To get it in you need some contortionist hands but how I did it was to lift the main engine harness up and stick your hand all the way down in there and prop it against the firewall somewhere. For me it normall wedges itself in there enough so I don't have to hold it the whole time.
As for the bottom, it is 20x easier to get it from the bottom. Again I used the 14mm closed end wrench to hold the nut, and then used a 1/4in 14mm socket with no extensions and took that off as well.
For me to get those bolts off, that is by far the easiest/fastest.
Great info tho jebus, good to know I'm not the onlt person who has done this...
EDIT: here is the TSRM stuff I found.
