Default Help with correct part number

I have a 71 base model- 350 4speed. I have been trying to track down the correct clip for the vacuum line right behind the master cylinder. Does anyone know the part number? I have been searching and just can't find it.
Thank you.Name:  IMG_1681.JPG

Hi HP,
It appears 2 different clips seem to have been used sporadically at that location.
I'll try to find the numbers.
The first I see in reproduction (try Corvette Central, HDL-319), the second only as used originals.
Regards,
Alan

This one, it's the same as those used on the left side apron for the vacuum hose bundle and harness:


And this one:

Not sure but could it be GM 3977708?
Is it the clip that holds all the hoses together? If so, I believe the 71 needs 5.

thank you. I have the one in the top picture but it does not seem right because I don't have the brake booster and it hangs over the master cylinder cover..

Hi HP,
I have seen the longer type of clip on cars without p/b and you're right the clip does extend over the mst/cyl lid.
The pic of the car with p/b is actually an LS6 restored by someone who's a member of this Forum and also a pretty special Corvette guy!
Regards,
Alan
