    For the shock mounts either reuse them or build new ones. And for the Perches, just get new ones! You can get them at Summit Racing for about $12 -$20 ea. Or any driveline shop should carry them!

    Also, when cutting that stuff off be extremely careful not to burn into the axle tubes much if you are using torches!

    I used a grinder to cut the welds and a bfh to help get them off. I reused the spring perchs on mine. For the shock mounts I cut a set off a junk 10 bolt and used them on the 14ff. The shock mounts are just temp. untill I do the long shock conversion.

    Spring perches? If I needed to move a pair, <a target="_blank" href=http://www.off-road.com/chevy/tech/perch/>this</a> is what I would do.

    Not sure about the shock mounts. Mine hang down and need to be moved. If you find a super cool solution, be sure to let me know. [​IMG]

    If you're careful, you can reuse them. I used a grinder to remove the perches and used a torch to remove the shock mounts. I reused my perches, but not the shock mounts.

    Mikey, I did the R&amp;R on Rocko's 14FF we traded.

    That rear was a true 1 ton rear and I used a 4" grinder til the perches came off. I also used a BFH to break them loose.

    Then used a stick welder, but can't remember what size rods they were. [​IMG] I welded a little at a time to allow for cooling so the tubes would not get warped.

    The shock mounts were done easily, too. Ground them off and used the same welder, too.



    I'm not picking my nose...I'm just pointing at my brain!! [​IMG]

    I have their catalog and they list them as "3/16 inch" thick.

    The stamped-steel perches on my '85 are something like 3/8 inch thick!! [​IMG]

    I would prefer to find some thicker perches like the factory ones on the '85 and newer 14FF's.

    Anybody know how to get some perches from GM like these massive ones on these rears?

    So just be careful not to warp the tubes... got it. I won't be doing the welding cause I really don't have much experience or equipment, but both the buds are licensed so they should know their stuff.
