How hard is it to modify stock control arms like that?

[Otto347]

You need the cups for the spherical bearings to weld in place of the stock ball joint. I had a jig setup in a mill to cut the hole for the cups. You need a good welder to weld them in and you need a $70 ream to ream the uprights for the studs.

$30 for the cups
$40 for the spherical bearings
$40 for the studs
$70 for the ream
$$$ time in setting up the jig for cutting the control arms
$$$ time for welding


Or you could just buy these that are already done.

Also here are some pics of my welds
