1970 Vacuum Hose Clips on LF Inner Fender- AIM and JG inconsistent?

[Mark E.]

Your input please regarding the number and type of clips (open or locking) located on the LF inner fender for securing the vacuum lines and front wiring harness in 1970. AIM shows three locking-style clips while the Judging Guide and several cars I've seen, including mine, use two open-style clips.

Below is the AIM showing 3 locking-style clips on inner fender and one on the fender's drip rail near the master cylinder. The clip missing on several cars seen (including the one photographed in the Judging Guide) is circled in red:

Photo from 1970-72 JG 6th Edition, p. 197 showing only two clips on inner fender. Note hole or dimple in inner fender for "missing" third clip. It's not clear what type of clips are on this car (locking or open style).

My 1970 #12931 has two open-style clips on the inner fender and one mounted on the fender's drip rail near the master cylinder. Second photo shows dimple in inner fender for third "missing" clip shown in AIM. Missing tape around hoses possibly removed by PO but hoses and inner fender believed original.

1970 #15192 seen at Frisco Regional. As I recall, it's unrestored with under 20k miles. It has two open-style clips on inner fender plus one on fender drip rail near master cylinder. Similar to my car but no dimple or hole for "missing" clip.

1970#6562 that was for sale on the internet awhile ago. It claimed to be an unrestored car with 75k miles. It has two open style clips on inner fender plus one on fender drip rail near master cylinder. This is similar to the two prior cars but has a hole in the inner fender for the "missing" clip.

Photo of 1970 taken from the internet awhile ago; history or VIN unknown. I chose this because it's consistent with AIM: three locking-style clips on inner fender. Looks restored.

Mark, your car likely shows how your car was built at the factory. As you said the inner fender looks original. You just need to tape the original hoses as the AIM shows to neaten up.

The pictures of the Marlboro Maroon 70 LT-1 in your post, out of the TIM&JG, sits in my garage. It's a garage king, original paint, 1988 Lancaster, PA. Top flight. I've attached a better picture, clearer and brightened. The front clip is a "J" clip. Tomorrow I can get other pictures if you want.

Gary
It might be worth noting the VIN or build date of each example. There were running changes to the vacuum harnesses during 1970 (filament tape for example).

It might also be worth considering Power Brakes or manual brakes. The third clip could be to hold the vacuum harness away from the power brake booster.

Your Maroon is "late". You have a blue "early" car down the road, and then there is the library. LMK if a visit to the library is in the cards. I want more learning.

Cold here this morning, when I left for breakfast a 5:45am, it was -2 degrees.

I'll try and go down the street and get pictures of blue car today. When it gets warmer. High of 28-degrees predicted for today!

Pictures are of 1970, July 6th build. "J" clip, no locking clips. In the garage, did not open the door for better light. Didn't want to get the car mad at me !!!

First picture is near master cylinder, "J" clip. Next picture is near the end of the Inner fender panel, empty hole. Last picture is the "J" clip near the radiator core support.

I reached the same conclusion after some confusion seeing the variety and number of clips used, hole, no hole, dimple.... The left front fender on this car was replaced in its distant past so I wondered if they didn't replace a clip. Now I know some cars have a dimple or hole.

I took the time to document in this thread what I learned to help the next guy.

Worth noting is AIM show 3 locking clips on the inner fender, while the JG shows 2 open clips (your car).

You have to remember that what is shown in the AIM is not 100% accurate as to what occurred on the production floor.

The red car in the first post is the only car I've seen with 3 locking clips like AIM shows. I wonder if it was restored to match the document or if some cars were actually built this way.

My 1972 has 3 clips, but that's a 72.

Right. By 1972 vacuum hoses were neatly stacked and routed rather than the sagging, messy installation seen in '70. The '70 AIM specs what we see for 71-72, but wasn't followed for many cars.

Just so months or years from now, if a person looks at this thread....
Attached is pictures of Terry's Mid-January VIN 2161 LH inner fender panel and vacuum hose clips. All are "J" clips. Hole in the top surround channel and inner fender panel not used.

And just for giggles, a late 1969. Motor delete right now. Built K09 (June), right after the strike. Vin 21,4xx.
Very similar to Terry's.

Thank you, Gary. The ice must have thawed so you could get to it.

Just a clarification: Trim tag date is A29 (January 29, 1970).
