  This one, by chance?

Here's a little rundown of assemblies and nozzles.  The 86 on do indeed use
the same assemblies for TD and NA!!! (rebuilt)

                                                Nozzle)         (New Assy)

96 1.9 (TDI??)  (???)    (with timing-->)       0-433-175-092
0-432-198-811
96 1.9 (TDI??)  (???)        (normal-->)        0-433-175-092
0-432-193-810
97,98 (Canada)  (1.9L)          --------        0-434-250-169
0-432-217-243
98 1.9 (TDI)        -------         (with)      0-434-250-169
0-432-193-695
98 1.9 (TDI)        -------       (without)     0-434-250-169
0-432-193-693

   That's where my book ends.  Seems odd that the 1.9 and TDI would
use the same nozzle but that's what it says in two different columns.
<shrug>
   Now if we just compile the DN (0 for 1.6 IDI's)  SD (___) numbers, we'd
have a complete comparison!  Cant find my reference on what those
numbers mean exactly.  The DN is the degree of spray pattern. 0 degrees
for the 1.5 and 1.6 engines.
  Oh what fun!
