Yes that is the correct gearbox but unless I'm missing something other than some parts there isn't a "guide"

No it's the single rail version of the 2000E gearbox

Does anyone know where I can find a decent diagram, manual, or something for the type 3 gearbox?  I've tried Cortina and Capri workshop manuals which are no help.  The best I found so far are a couple of unlabeled drawings on www.bearingkits.co.uk but they're not that helpful.

The gearbox is having a hard time shifting into 4th.  It seems to be a little smoother if I slam it over to the right side so maybe its a selector fork issue?  Removing the shift lever didn't reveal anything so  I don't think I can see a damn thing without taking out the engine and entire gearbox so hoping maybe a detailed diagram will help me diagnose a little before committing to removing everything.
