Anyone swap their trailing arms?

I bit the bullet and ordered the ones from ECE..... Then also added 6" drop springs, the super trac bar and the shock relocator kit... Hope it's pretty sweet!

on my "72 short step project, i took some low miliege ones i had saved , separated them , blasted them , box the front end, welded them solid , along with plug welded where the rivets were, all while they were clamped up . then por-15 them ,and installed energy suspension poly bushings ... i thought about plating them yet i think it will be fine. i got mild 455 buick , 400 turbo with 3.73's with an auburn ... uh , 3" cpp springs , 1" block , ece deluxe track bar...

Just an FYI, if any of these tubular arms are capped on both ends and don't have weep holes in them you better drill some. They may eventually fill with moisture and freeze and exspand or even split.

I aggree but will add that they will rust through too. I use to work for a company called Hancor Inc. They manufactured plastic pipe from 3" to 56" in diameter. Every size had its own tooling. We made tooling stands that could be easely rolled around and in the larger stuff we had to build racks to transport it in. some of the large stuff was shared between a couple of plants. Anyway we use to build them out of square and rectangular tubing and would paint it with rustolium paint. After a few years of use we started discovering rust holes in the lower ends of the tubing and this tubing in a lot of cases was 1/4" wall because the dies that it supported wayed well into the thousands of pounds. After cutting some of the rusted tubes off to repair the stands we looked inside them and discovered that the whole inside was rusted. When we built the racks and stands we would always would plug and weld the ends up tight to keep moisture from getting inside. What we in fact were doing was trapping moisture in them. The moisture in the air that would form condensation, witch would in turn cause the rust that eventualy go through the steel. The fix to our problem was to not only drill weep holes in the tube, but we also drill vent holes so air could flow through and dry the condensation up. Once we did that the problem went away. WES

Good call on the vent portion, never even thought of that.
