Vince, the gold one is a model A.
IFS was later taken off and replaced with beam/tube.
Problem with the se5 is the wheelbase is too short for an A or B Ford body, plus side is that it would be road tax free.
se6 is a longer wheelbase and more suited, however I doubt you would have room for front fenders if you stayed with the ugly IFS.
Willys body fits good on one of these (not sure if its the 5 or 6 model)
