Adding to "Carolines Truck" post about dropped axles,I have a Mor-Drop axle,,,good product, but it took him forever.His blacksmith shop is quite an interesting place to visit.
I recently bought another one from www.droppedaxles.com
Sid Drapal is a great guy,gets the job done with no bull malarkey and is right there with tech help! He does most of the larger swap meets and has a really good selection of different axles.
