i got a 89 1/2 ton ford with a 12v cummins, manifold flipped over, he351w mounted up for my top turbo, my hx55 that im gunna use for a bottom turbo has a t4 flange on it, i need the weld flange to clamp to the he351 and i guess a weld flange for the t4, where do i get those pieces? i would like to say id just get a aurora plus 4000 kit but i dont know if it would fit in the ford with the ac box there in the way and theres no way im sacrificing ac for twins (: and if the kit dont fit in there then i just spent 3400 bucks for nothing i called and the aurora 4000 turbo is a t3 flange so i cant use that piece anyways
