Auto to manual swap., My reluctant journey. Options

[WannabeGT4]

Alright I've done the automatic 3SGTE and it was great while it lasted... Second gear just disappeared one day so I think I'm just going to go ahead with the manual swap instead of trying to install a built A540E to replace the stock A140E.

When I bought my celica a few years ago it came with what I was told was everything I needed to do the auto to manual swap but the seller ended up being less than trustworthy so I was hoping you all would be able to confirm that these are the parts I need.

The clutch pedal doesn't spring back on it's own when it's in the depressed position. Is that normal? I assume so since the hydraulics are dry and the pressure plate isn't offering any resistance.

Also, Can anyone tell me what in the hell this transmission came out of? I know it's not an S54 and it's not from a Camry or a 4th gen Celica but maybe it's from a 5th gen. I need to find out which car it came from so I can get the electric speedometer sensor to replace the cable driven one.

I'm not sure about the drivers side transmission mount either. Does this one look like what I need or do I need to find one from the S54 out of a 6th gen.

Lastly, do these cables look like 6th gen GT shift cables?

Thanks in advance.

The flywheel and clutch are MIA but I'll be getting a spec clutch and hopefully a lightweight flywheel.
