Try your local parts store(Kragen Pep Boy's Napa) they might have the right puller. Also if you can skin back that boot and clamp a pair of vise grips just below the colar. Leave enough roon for a larger straight slot screw driver or pry bar.So take a hammer while prying up with the screwdriver against the collar just tap the steering wheel shaft.You may need an extra set of hands.You will know right away if this is gonna work. Don't go crazy.Hey you can always bring her up to Monk Marine and I'll Get r Done for nuthin.
. Good luck
