well, this is kind of embarrassing but . . . . the simple 'trick' is : needs to be dropped in from above - i was trying to work it in from below - oops - sorry for the bother - thanks though - by pulling the side cover it gave me the opened up space perspective causing me to try dropping it in that way. just didn't remember that it came out that way. now i know. on to the boot replacement.
a trick on the boot cover...apply a little WD40 or grease to the lips of the boot. You will put the front on first, then work at the back. it is a BITCH!!! to say the least...but keep working at it and you can get it on with your hands.
