    I am doing 56's with an echobit flip. I need to replace all the bushings in both springs and at th shackle as well. I was reading on the site and it said for 56's you must measure because some are 1 1/2 some are 1 3/8 and some are 1 3/4. Where exactly am I measuring this difference? This is for an 89 K5 and I believe the springs are from an 89 3/4 sub.

    Also how do I know if it's metric or not since I am working with 89's here.

    This is where i was reading

    I did the same thing on my 87. You need to measure the inside diameter of the spring eye itself. Like the link says if it is metric it will be almost 1 3/4" across. I just used my plain ol tape measure to do mine and it worked out fine.

    Mine look to be 1 11/16 inside diameter with the sleeve removed.

    That is bigger than 1.5" and pretty close to 1.7" since 1 .75 is 1 3/4 or 1 12/16:D . If I had to make the call I would say you have metric springs:D . Make sure you measure all 4 of the spring eyes as GM has been known to mix and match.

    Yeah both ends are the same. I figured

    1 11/16" = 4.28 cm
    1 3/4" = 4.44 cm
    1.7" = 4.31 (metric size)

    Mine measured 1 11/16 so I ordered the metric since I triple checked and 1 3/4" is too big. I hope they are right or Blazer Fest might be out for me:crazy:
