Removing the ZF transmission to inspect clutch wear and flywheel play. Couldn't hurt to replace both.

Friend helping out, removing flywheel

Dry rear main seal, surprising. Still replacing it.

Driveshaft, slave cylinder, and linkage disconnected. Cross member being loosely held until pull.

Exhaust done, engine mounts done, oil cooler lines done, entire driver's side free sans the fuel lines.

EDIT (11/27/2013): I have been sourcing the last of the swap parts as well as the refresh/replacement parts needed for the conversion. The list is pretty long so I've been compiling a spreadsheet to keep track. It's preliminary and I still have some stuff to add depending on what problems I experience (shifter parts, etc) but I figured I'd get it up. I will post the final list (reset) post swap. If anyone sees any errors, please let me know so I won't be surprised during the swap!
EDIT (02/18/2014): Finished with the swap a little while back. Here is the final version of my S52 OBD1 swap parts list. All of the part numbers should be accurate (unless they become superseded).
EDIT (01/05/2015): Replaced the S52 specific swap list with my master e30 parts list

Also, here is the (reset) Excel spreadsheet, if anyone would like to use it as a starting point: dropbox link
