I installed their CTA-31A uppers and the CTA-31H lowers on my chassis. They bolted up without any issues and the del-a-lum bushings get solid reviews. They are heavy so don't look for much, if any, on weight savings over stock arms. I did have to trim the rear of the inner fender openings a little when I put the body back on (all of which will be hidden by the dust covers). Its a roller at this point so I can't comment on any of the adjustability just yet.
I have the extended travel coil over lowers and the uppers. I am using Ridetech coil overs with them. Love them. Really sturdy and as said above, love the Del a Lum bushings. No fitment problems here on my 69, and plenty of caster.
I pulled one side of the front suspension, and threw away the old A-arms, then found a different chassis. So the front left quarter of my 79 roller is sitting on a Global West front LCA, just so I can roll it around the garage. This is the one with the 2" drop specifically for coil overs.
I'm looking forward to getting some use out of them, in my other car, someday.

The Global West LCA's came with lower ball joints, which is nice.Looks like I'm missing one of the two SPC UCAs, so I need to track that down, not that I can do both sides of my car without turning it around...
The only issues I have encountered. The Globalwest upper control arms are 17 1/2 inches wide and require removing the inner fender dust shields and may require some trimming of the inner fender. Not easily installed with body on the car. Otherwise this is a very good upper control arm.
I know this post is about Global West arms, but for comparison purposes, and looking at bikespace's picture, what advantage do the SPC curved upper arms have to the straight arms shown? Looks like there's more clearance. I note the straight arms (which I have) have no bump stop, maybe these
I didn't chase down much on GW uppers for comparison purposes, but it looks like they need shims to adjust? SPC's design seems like a considerable improvement.

I thought I was done with shims. SPC doesn't make a solution for the C5, so my SRIII chassis will need shims! Yuck,
I think the curved SPC arms provide more clearance, such that they don't hit the chassis before the limit of shock travel. The straight SPC arms likely don't hit, either, with semi coil-overs. It seems they are a bit shorter than stock shocks. I'll have to check again when everything is bolted up correctly.
