Info on drop shackles for '67-72

[brossow]

Just got a pair of 1" drop shackles delivered from CPP today for my '72 C-10 with rear leaf springs (obviously). Expected them to be custom-made shackles like their 2" drop shackles, but instead they are off-the-shelf parts from Flagg.

The Flagg part number is E747-22, which is the same as some other company's part number 330-180 (don't know which manufacturer at this point). I have no idea what the original application is.

Did some searching online and found the same shackles available at Stengel Bros. for less than $20 each, compared with the $44/pair I paid CPP. Not a huge price difference, but if your budget is like mine then every dollar counts. I could have used the extra few bucks, so I'm passing the info along in case someone else can benefit from the info.

EDIT: After pulling out the old shackles and comparing them side by side with the new, I fail to see any difference whatsoever and don't understand why/how they can be sold as 1" drop shackles. Not a huge deal since my goal was to replace the shackles instead of cleaning up the old ones and the drop wasn't important, but still. Compare the pics...





EDIT #2: See my message below. Turns out they sent the wrong shackles and the ones pictured are stock replacements.
