i needed to replace the solonoid in my sedan and of course i couldn't get
any of the three phillips screws to move or the top bolt out of the starter.
i took an air grinder and mirror and ground out the solonoid screws. messy and ugly what it did to the aluminum housing, but it worked. then i put the new
solonoid on with socket bolts. if i have to go at it again, cutting a hole
in the fire wall makes sense. there was one in my 300 w115.

when i put a new engine in my coupe, i used hex bolts for the starter and
socket for the solonoid.
