My 37 has an emergency brake handle like the one in your first picture. If you couple the first picture of the brake handle you have along with the drawing on the right side of the illustration that Joe H posted for you, you'll see you have the correct brake handle. The two holes on the saw tooth pawl you have attach to the right side of the stock transmission. With an automatic transmission, you will have to make a bracket to mount the emergency brake handle to. The release part of the handle faces the back of the vehicle. From there you can see the part that the rod with the big spring attaches to that Alvin writes about. That is about all there is to it. Hope this helps a little more. Good luck!
