Full StarFull StarFull StarEmpty StarEmpty StarOrder come as expected!!!
by Herbert from Potosi, Wisconsin on June 28, 2015
I ordered (2) SETS. (1) SET WAS OKAY. THE OTHER SET WAS NOT OKAY. I HAD TO PRY THE MOVING PART OFF OF THE PIN AND USE A INDEX DRILL TO DRILL THE HOLE TO THE PROPER HOLE SIZE. MOVING PART WAS PRESED ON TO PIN.

great fast, correct service with very reasonable shipping. Will order more parts. (sorry I mistakenly gave it a wrong rating on my first review 5 being the best, not number 1).

My Merc has 2 sets. Contacts did not line up real well on one set of points but they work fine.
