Exhaust manifold

[V12Bill]

I just cleaned,resurfaced and painted my exhaust manifolds in my 1950 F1. However the engine is an 8BA, and not an 8RT. When I bolted the left manifold in place, I noticed that there is only about 1/4" clearance between the manifold and the steering box. Is the 8RT manifold different than the 8BA?

Thinking if your truck pipe fits you are good to go because I have 3 8BAs from a car
and the car has a cross over pipe tottally differerent.
