Will the 84-85 or 86-87 turbine housing swap onto an earlier 78-83 draw through turbo? Is the turbine wheel the same diameter and contour to work or will it have to have a matching wheel from the other year of turbine housing?

Thank you. I thought that might be the case. I think the only downside to swapping an 84-85 turbine housing is the 78-83 turbine housing has ears with mounting holes on the bottom for a bracket that supports the turbo on that side of the intake manifold. Looks to be a huge improvement in exhaust flow swapping to the 84-85 turbine housing and wastegate elbow.
