Haha, no, I'm not using original A-bone brakes! I was intending on using the Mercedes rear out of whatever donor car I get, provided it fits ok. Up front I am using a drilled straight-axle out of a Dodge A100 with a transverse leaf, and of course an adjustable proportioning valve to balance things out. I think I'll probably go with the 616 or 617 engine like you said, what did they come in? Man, ain't I all full of questions?
