The #336-1860 (that takes one long & one short bolt, straight across from one another) is for use with the smaller 12-3/4", 153 tooth flexplates. Even if your engine block has the holes to accept this starter, it won't work with your existing flexplate.
Sorry I didn't get back to this sooner. This week was our small town's summer celebration so between doing stuff there and getting the convertible polished up for the parade I didn't have time to do anything online.

My truck isn't a daily driver but in the summer I drive it nearly daily.

Funny thing about the flex plate. I recall now when I pulled this 307 out of my Chevelle in 1989 or so, and put in a 350 I refreshed in its place, when I went to start it the starter was not engaging the flexplate. Back then Midway Chev on University in St. Paul was close by so a quick trip there for the larger flexplate fixed the problem.

Sorry. I'm easily sidetracked.

I will see what the jungle website has for deals for that #337-1011 starter on prime day.
