I'm making an air-scoop for the radiator. I have seen the schematic with #15 in the WIKI parts list, but have not seen one on a car.

Anyone got good pics of its clearance in the tie rod area and the mounting points?

psst: I'm trying the snow shovel idea (taking lots of pics in case the dang thing works out).

I'll look for in-car pictures

I'm up for a lesson this morning. Explain why clearance in the tie rod area is important.

I went out and looked at the 70 and the scoop is mounted to the bottom of the chassis just in front of the radiator and the bottom tab at the front of the radiator.

Parts lists call it "Assy, Cross Rod". Connects to the two steering arms. It moves in an arc but essentially moves fore and aft from the frame as it does so. The scoop needs clearance or it could bind. I can use the static position, but thought it wise to review what the orignal designers felt was a good spacing.

Gotta be something different. The radiator scoop is shown in the parts manual as GUIDE-AIR, mounts elsewhere and does not move.

What the parts list picture doesn't show well is how the Air Guide is actually mounted, nor to where.

It gets mounted with the curve inverted to what you would imagine. Instead of the leading edge of the "shovel" leading INTO the wind, it actually has the edge pointing DOWN. It isn't set to "slice" INTO the air stream, but to "dam" it up and into the radiator.

I'm attaching 3 pictures of the guide installed on my car. The guide's mounting tabs do NOT allow for mounting it the other way.

The Cross-Rod that you are referring to is visible BEHIND the Air Guide, and in this picture is located at it's most forwardmost position. Any movement from here would be further aft and as you can see would not interfere with the Air Guide.

Hope this helps.

Perfect...exactly what I was looking for!!! Thanks much!

I'll post the end product (when I can get my bud to tig the tabs).

It's all done and mounted. Pics of the process are in Photbucket.
$17, 2.5 hours, and personal satisfaction. $23 if you count the Harbor Freight POS cutoff tool. Works very well. The reinforcing ribs are what gives it strength over flat/curved aluminum. If I do it again, I'll drill strain reliefs adjacent to the tabs before bending them.

That's great. It's one thing to sit at the computer and observe "It looks like you could just make one with a snow shovel", while it's something else to actually do it. For style points, put the decal from the shovel handle on to the scoop
I watched Sid make an exhaust manifold heat shield from a "borrowed" New York trailer license plate, it was a classic repair.

A little late, but here are some photos that I snagged off the net showing a custom air scoop:

My car is missing the air guide. Does anyone know where to get a custom air scoop? Besides the side mounts that bolt to the front frame cross member, where else does the air guide bolt to the car?

Is this custom design as good as the factory design?

I don't know where you can get a custom scoop. It bolts to the frame and to a bracket that is soldered to the front bottom of the radiator. Some have gone missing over the years. I would think that the custom design is as good as the original, but I haven't given it a lot of thought or consideration. I am sure that an engineer will chime in at some point. Looks simple to make.

My radiator doesn't have a bracket on the bottom for attaching an air guide. Does anyone have a photo of the bracket on the radiator?

R, What rad do you have?

Either way, I wouldn't worry about it, gale force air comes through the grill. They really aren't necessary.

If you really want one, we have plenty of nice used. (We can have it blasted and painted/powder coated if you like)
