Air bagged 68 c10 help

[Gav2606]

hi . I purchased a 68 c10 with airbags fitted already, they have never really sat righyt its had the top plate bolted to the under side off the top arm which is correct, the bottom arms have been changed to a tubular arm as it runs later discs and calipers, for the bottom on the bags they have welded a plate over the spring cup and bolt the bottom bags in place, i have just replaced both front bags with d2500 airlift which is what was in the incase it was the bags at fault. But they are doing the same. Should i remove the plate and get the correct cups to sit in the spring base.? It just doesnt see inline? And advise greatly recieved. Many thanks..
