HQ-WB roof spoilers (duck tail) can you still get them?

Agr071, I scanned in this photo of my van at a show in the late 1970s.Attachment 4933

I can't make the picture out properly... Are they quad or dual sidedraft webers? Either way, looks trick!

Dual side draft twin choke 52mm webers as I recall. The bore size may be incorrect (failing memory), i know they were too much for the motor. You could almost run another car on the amount of fuel that came out of the lakes pipes when you floored the throttle.

Thanks for that.
Would have looked great in the day!!!

This one is a bobtail spoiler? Came with the most recent van. Luckily it was only tech screwed on. Very easy to remove
