I am trying to locate a pair of correct disc brake calipers for my '70 project and can not find the correct part#. Can anyone help with this and possibly know where I can find them? Thanks.

These were unique to 1970 Camaro/Firebirds w/Ft.Disc only,as 1971 & on saw many newly designed revisions.
1970 Left front #5470121.. beginning w/1971,#5472532.
1970 Right front #5470122..beginning w/1971,#5472533.
Bear in mind that these part #'s are NOT the same as the casting number actually cast into them.These are merely the shelf ID part numbers the GM placed on them in.
Someone who owns any one of these cars,could probably tell you the actual number cast into the caliper..

The two I took off my 70 camaro casting #s are Left # is 5470126 & r # is 5470125. I don't think these are org to the car. The disk hub is dated B 14 70. My car didn't have front brakes when it was ran back then.

I found that the correct casting numbers are, per Ron Norman, if anyone cares or wants to dispute:

6470128 rh
6470126 lh

Ron has a buddy who took these off of his original '70 L78

Does the "70" in the casting # denote the year?

No,the "70" in the box number does not denote the year.That's just a coincedence.
I'm with Kim..that's the number 5.

Kim,

I agree that your pic looks like a 5, I will post a pic of the number on the calipers I bought when I get them. I really have no clue which is correct but am at the point that I will just go with what I have. I appreciate everyone's input and it's not like this is a life or death issue, unless they don't stop the car when I need them to!

The correct casting numbers for 1970 Camaro calipers are 5470125 for the left side and 5470128 for the right side as shown in the pics below

The casting numbers on many 1970 Camaro calipers are very difficult to read. The first and last digit of the 5470125 casting number can look like the number 6 when in fact they are the number 5 as shown in the pics below

The first digit number 5 of the 5470128 casting number can look like the number 6 with a really bad casting but with a more crisp casting the actual number is 5 as shown in the pic below

The big problem with the number 5 is the bottom curls around almost to the point of connecting and on some they do connect which makes it look like the number 6, however a 6 is curved at the top and the number 5 is straight across the top

I have included pics of 1970 Camaro calipers with the best looking casting numbers to show they are in fact 5470125 L and 5470128 R

Very good pictures.
I think the right side is actually 5470126.

I thought the ride side was 5470126 also but all my of 1970 Camaro calipers show the number 8.

Here are two more pics of the right side which shows the last digit clearly as the number 8 not a 6 and the casting does not look like it has bled into the number to make it an 8

Compare the number 6 in the 1st pic below in the casting mold number "GM 16" to the last digit 8 in the 5470128 casting number and they are different, the last digit is clearly the number 8 not a 6

The number 6 has a larger top circle where it curves around the top and stops to form the 6 whereas the last digit 8 in the casting number 547128 has a smaller circle where it curves around the top to form the top half circle of the number 8

The two circle halves of the 6 are closer to the same size but the number 8 has a large bottom circle and a much smaller top circle so the casting reads as 5470128 not 5470126
