Pat that truck cab looks like it is a 73 or newer, and that may have been changed over the years. It has the rounded in highlight line in the door and cab. The front looks the same as our old 68 bus we had for a camper.
Pat this was the first time Dad had been fishing after the stroke in June. It was a bad fishing day but a good day to see him do fine by the water and using the fishing pole. Steep banks and uneven ground he did fine. I did have to take the fish off for him though.
Jeff I would think that any motor about the same size would work. You will just have to adjust the hold downs. This will not be a long term use motor so just wing it.
I say spend some time in the question and answer section in the forum also. A very large group of info in that section. Start slow no need to paint the first one. Follow Tom's invite and go join his group. Face to face is better and they might help out with some cheap bodies to practice painting on.
