Gen 1 Spring Perches and U-Bolt Plates

Gen 1 Spring Perches and U-Bolt Plates

Postby AstronautFireman [OP] » September 10th 2017, 12:09am

Hey guys, doing a rear S10 spring swap on a gen1 '91 safari. I ordered the Crown Automotive # 52006421 plates as mentioned on astrowill's website. the plates are a bit too narrow to fit over the perches, even with significant grinding already done. To get the bolts to go through I'd either need to cut or drill out notches into the existing perches, and that doesn't feel right. Does anyone have experience with this, is there a different plate that has been used that might be a bit wider?
Thanks!

Following the link, and scrolling down a little leads you to: viewtopic.php?f=127&t=11729&start=200#p723162

That post shows you where I drilled the plates to convert from composite to steel leaf springs.

As long as you don't grind away the sides of the existing perch, you will be fine. If you have already ground away the sides of the perch then you can order the Coreswest perches listed and weld them on.

I opted to go with 3inch wide plates seen here

I think they sell 2.75 in wide also.

I decided to not drill the perch surface and instead do some grinding on axle. I am ok with a gap on the sides of spring. No pics of mine but look through Lumpys spring pack build, page 10, and see how his turned out.

not really, its mild thin steel. drill a 1/8" pilot hole in 4 seconds, then step it up in a few more seconds.

Yep, doesn't take long at all, even quicker with a plasma ;)
