Along with NAPA, another place you can try is CarQuest....No Kiddin...The regional distribution center is in Lakeville...I-35 south to Co Rd 70. Go east (left) 2 miles to Grenada Ave. Place is on the South East Corner. Call em. They have had EVERY part I have asked for for my 46 1/2 ton. The guys at the store attached to the warehouse are patient and a good bunch. No, I'm not advertising...just telling another bolter what worked for me. If you need a part in a hurry, this is the place to get it "south of the river". The warehouse is obviously HUGE..sort of like bolters heaven. They are a little pricey though...
