The OE starter is a 16 pound turd. Here's my IMI hi-torque-8 pounds and bulletproof. Robb's is beautiful but too much $$.
What you'll see;
Good time to send the flywheel out for a .005" or more cut. Mount the block plate, then the f'wheel. Bolt starter into it's nest. Hand test the mesh and shim if needed. This was perfect.
See the scissors under the pan? Use a wood block between.
