1971 A Body Brake Booster

1971 A Body brake booster looking for the correct one. Is the one in the picture correct.
Can someone post a picture
I know what 67 to 70 look like, just not sure on 71's
thanks

For some reason my pictures are not showing up.

They used that booster thru 76. My 73 Scamp has one.

so 71 to 73 A body booster are the same

Yes and I parted out a 76 A-body a few years ago that had the same booster too.

Thanks

Survivor 71

Do you know the build date?

Do you know the build date?
My car is missing the brake booster and master.
My build date September 26

October 6th 1970

Here's one on a 72 Demon

thanks

Yes proper booster is a 7-1/4 inch unit, they are rebuildable from Booster Dewey. There is also a 7 inch unit that is not rebuildable. The larger units were first installed in 1973.

Well alrighty then. I stand corrected.

Can you see the difference in 7 inch and the 7 1/4?

The difference is there is a removable band around the 7-1/4" like Scott shows above. The 7" is crimped together.

No B51 on the tag!

Disc brake car?

Yes, power disc brakes, 2900 original mile car.

thanks

Wrong master cylinder.

I am told that there are two brake booster a single diaphragm for drum and dual diaphragm for disc. How do you them apart? besides taking them apart?
Thanks for the help everybody

I called Dewey and he told me the single Diaphragm is different shape plus 9 1/2 inch. He did also said the 67 to 69 are 6 1/2 inch and the 70 to 71 are 7 1/2 inch

I have an NOS one just like the one in the first picture at the beginning of this post if you are interested.

yes I am, sent you a pm
