Stock tubular upper control arms

I have a 90 chevy pickup and was wondering if I can use the 4X4 control arms that are tubular or do they have to be the 2wd ones?

they have to be the 2wd...im assuming your talking about 3/4 ton upper control arms...

Yeah the 4wd ones are tubular also but I wasn't sure if they would work.

no they will not work... the 4wd arms mount on the outside of the rail and the 2wd arms mount on the top of the rail like yours does

so what ones do we need to so we can get stock tubes? will they help on the camber?

3/4 and 1 ton 2wds have stock tube upper arms but i believe the are the same lenght so no help with camber
