Hi i'm Wayne
I will help you with this
remove battery cables, take a PIC of wiring so you know how to put back on
remove alternator , to get better access,
use long extension bar to get at starter bolts,
have another person help
there is a panel under the seat to get at starter

do you think it might be the starter or bad connection?

If it does not start
try cleaning the connections, battery also
also jump the starter post key on, battery stud to small stud

we got it opened tapped on the solenoid and it started to turn over so I will order a solenoid tomorrow.
