Fuel Distributor Differences between CIS-E('85-87 4kq 5 cyl KX) & CIS-EIII(post '87 5cyl NG)

[Ben Swann]

Today's question: Regarding the install of complete NG  setup into 4000Q -

Are there any differences I should be concerned about between the CIS-E on
a '85 4000 Quattro and the NG CIS-E setup - in this case from a 87.5 GT
Coupe?  I have both, but they appear identical.  I'd hate to go through the
trouble of swapping the fuel distributor head if there is no difference.

The fuel distributor came with the NG engine but I didn't get anything
below that, so I'd have to swap with the airflow sensor plate assembly
below on the 4000 if I need to.  Id hate to take apart any more than
necessary, however and my gut tells me these are the same - they look
identical.

TIA for answers from the Bosch Fuel injection wizards.
