70's F250 a/c box vs turbo

[CaliDieselGuy]

For anyone that has done a ford cummins conversion... I am looking for some solutions for the a/c box vs. turbo clearance issue. I know fordcummins sells a turned down manifold, but I would like to upgrade down the road to a performance manifold and turbo so I would like to stay away from theirs.

Didn't realize that this post went through, thought I cancelled it. In case anyone has this same issue, I decided to junk the stock a/c heater box, close up the hole in the firewall and go with a Vintage Air universal a/c heater system. Much smaller and more efficient then the old stock system. Not planning on purchasing till May/ June so if you are interested in pics or results please let me know and I will post again once I get it installed.
