69wagoon

My best friend has gave me a 69 510 wagon with a 81' napZ motor w.trans out of a 81 Dat. wagon that he never finished. My younger brother and I are having problems finding what kind of webber carb and intake to use and what to use for a exhaust manifold. The eletrical is getting close to being done as well. I have seen that some people have used the KA rad in there Dat. too, and would this be good for this car? Looks like the inlet and outlet are on the side I need. If anyone has any suggestions on what to use for the intake and exhaust it would be great. This is my sons first car and he love's the Dat. like me! Thanks...
