Heater control valve location

I have a '71 big-block A/C truck with new inner fenders and want help properly locating the heater control valve. Does anyone have good photos or dimensions of where this is located. I have photos that give me an idea, but I'm hoping for better info.

Dan

You can barely see it under the other hose. Should be on passenger side fender. Has a vacuum hose hooked to it and screwed into the fender well.

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: Heater control valve location

Some fenders have the dimples in them for the valve. Here is another picture.

Big block, small block the fender is the same. The mounting is the same spot no matter. Mine went where I put it wasn't worried about factory correctness. If you have the dimples then that's where it goes if not just put it in at a spot you like as I did. Well I guess if you can get some one to measure for you that would work also!

Re: Heater control valve location

Joesjunk, what is that sheathed wire that runs parallel to the heater hoses?

Thanks,
Larry
