With much effort I was able to follow the Photobucket 'how to' pictures. Again, great job! How did you connect the trimmed down GG1 one axle truck frame attached to the GG1 power truck? Epoxy, Superglue, Other?
Do you have another source for your instructions how to modify the GG1 chassis for the little Joe? The website above that directs you to a photo album site is unreadable and unusable. It is clear you did a fantastic job, and it would be great to see how you did it!
