here is the frame with the new motor installed: [img]http://akpierce.20m.com/tunnel%20project%20motor%201.JPG[/img] this is just a drop in installment. the only special thing you have to do is add a shorter driveshaft going from the motor to the lead truck. the long driveshaft works fine on the rear, but is too long for the front. i ended up using the shorter driveshafts out of one of the new Athearn SD40-2's that i scavenged for the long range dynamic brake housing that i am using on another tunnel motor. but i think you can order the driveshafts from Athearn. the power leads to each truck just slide right on so you dont have to do any soldering there.
