Thanks heaps Jen - that is where most that i have seen have them. There are just some that i have seen that have them mounted on the roof just above the windscreen, and some that dont appear to have any at all.

From my research and from feedback from helpful people like you i can assume that all HZ sandmans had the factory antenna in the front passenger quarter panel.

Must be an asthetic thing to have them on the roof??

Was the radio an option back in 78? This may explain why some vans have no antenna at all?

Thanks again Jen
