Throttle return spring

I recently purchased a 67 van. The throttle return spring is not there. Can any one tell me the location and possibly what it looks like? This is a heavy duty van with the 240 and automatic.

There is one that will hook from the throttle lever (under the floor) to the front apron, it is approx 4" long from spring hook to hook. I cant remember the spring rate. There is a second one sometimes that goes from the carb linkage to the front of the manifold. It's longer and with a lower spring rate, I dont know the exact distance (at work at the moment!).

I'm pretty sure this is not stock but prior owner had it hooked up with a piece of wire, I updated with some threaded rod, it works great!

On the 170's there is a spring that goes from the throttle pivot arm mounted across the floor pan to the bumper on the passenger's side. But the 240's have a throttle cabl and I have no idea if there's a spring under the front or at the carb. I would guess at both.

Is your cable getting sticky?

Thanks for the reply. I was thinking it attach to the body.

Sorry it is the body, towards the bumper, there is a hole there for it below the grill

I make and have the 240 cables in stock,, however I have always put a spring from the apron to the linkage to pull the cable fully rear wards,,, The stock spring fulcrum support piece works ok,,,,,,,, but the spring up front takes out any and all slack in the cable allowing a more consistent idle speed when you come all the way back down as it is pulling on the cable and not the carb linkage... it gets any slack thats in a cable out of there,,,,,

Like he said. This is mine.
