Hi everyone. I'm looking for rear shock replacement for my '70 Laurel. I'm hoping the 510 rears are the same (or very close) to the length. I took mine off and measured, it's 23" from the center of the bottom mount hole to the top mount point (not the threads past). Could someone please tell me what the stock rear 510 shock length is? If very close, I plan to get the Ground Control rear coil overs.
