Yeh the Designa Chassis "empire" is just Iain. He does shows and stuff so he's not always home.
A 110 chassis won't fit your Series bulkhead. You'll have to weld Series outriggers on. If you find an available used 110 chassis in the USA and it's not a pitted rusty mess consider yourself extremely lucky
If it were me, and I was facing this again, I would take my Series chassis and alter it for coil suspension and do the mods you want. Then I'd have it chemically derusted (inside and out) and then galvanize it.
Have a look at Shayne's 130 build. He just had Brian make up a total exo-cage for the truck and the rear box.
