Help me identify..

[redrider121]

Hey guys, I really want to do the 64" chevy spring swap and shackle flip, but I can't figure out how to identify between the two.

Yes, I have read everything in the tech library and both say they come off a chevy/GMC 1500 - 2wd preferred. Also, the 63 swap says 88-98's, so I'm guessing 99- have the 64's?

Thanks

Perfect.

So somewhere along the lines somebody didn't measure correctly and wrote 63"??

Could it be that the eyelet centers are to be 63 ? that way the shackle is always over center in the sprung position ???

No Idea, just a wild guess.
