C20 with Qa1 suspension

Has anyone bought the full qa1 suspension and installed on a c20? From all my research it appears front crossmembers are interchangeable between c10s and 20s but I want to make sure before dropping the money on it. I called them and they aren’t sure. I’ve also looked into RideTechs air and coil full suspension kits as well and they had the same response. I have leafs in the rear and am wanting a great driver as well as to lower it some.

I put a c20 crossmember on my c10. The only difference was the upper a frame bolts were bigger. I drilled my a frames for the bigger bolts all back together.

Thank you! That is nice to actually see someone that has done it not just a claim. Looks good
