you can try the automotive starter but in alot of cases they just won't work.
things you need to pay close attention to are the nose piece, the bendix gear teeth. You verified on the site info the bendix teeth count is correct but you still need to double check that when you physically see the automotive starter. The nose piece is the other thing... make sure it is positioned in the same position and also make sure the part that fits into the bellhousing that holds it in place inside the hole it fits in are the same size and also look closely at the nosepiece shape and thickness.
In alot of cases an automotive starter may look like it will work until you run into any one of those things i mentioned above.

So basically you would have to take the old starter with you when you go to purchase the automotive one and insure everything is a match.

Do you have a starter rebuild shop anywhere near you?
Most of the time they have those starters already on the shelf rebuilt and you can go swap it out. The cost of a rebuilt one isn't too bad compared to a new one.
