nice start to your project. that Louvre must be pretty rare. is it branded? any idea who manufactured it?
I can identify your grill as from the early type sprinter sedan. the S badge = sprinter.
See this site for japanese E7 model specs http://www.group5-web.com/e7/
For your radiator, consider getting an alloy 90 degree bend welded to the top outlet. Then the top radiator hose fits on transversely instead of interfering the vacuum advance diaphragm on the distributor.
Also you will improve your fuel economy if you attach the vacuum advance on the distributor. Since you have sidedrafts you'll need to connect a port from each runner into a distribution chamber, then from there to the distributor. All four runners may be too much since the factory pipe runs directly from the primary throttle near closed throttle. so try a port from #1 & 2 first and check it with a timing light to see if it's working. It'll advance the timing at idle and low load situations, -improving fuel efficiency, but should retard timing under load. blip the throttle with timing light running and you'll see the timing retard back to base timing momentarily. Refer to the 3t workshop manual to check vacuum advance matches the factory spec.
hope that helps
