Resolved 1g fwd question - lost synchronizer keys

[Breadvans]

I’m in the process of putting my transmission together and i lost these parts. It’s these little rectangles that hold a clip on, but I’ve also seen on others transmissions that they don’t have them? So i was hoping someone could identify them and how to buy them? And then also elaborate what they do and if they’re necessary? I drew a pic of one of them. There’s 3 that i had

If it's the solid metal rectangles (small box shaped) that I think you're pointing to, they are the synchronizer keys. Yes they are crucial and you must have them or it won't shift properly (keeps synchronizer sleeve in proper alignment). PM Twicks69 for them.

Don’t forget the spring.

Yes there is 1 spring (looks like giant circlip) on each side that holds the keys.

Don’t forget the spring.

Like the circular clip looking thing? Or is it a legit spring?

 

[luv2rallye]

He means the circular clip looking thing that sits in the hub (1 on each side) and pushes against the keys. It's called a spring because it exerts a springy outward force against the keys.

Okay yeah i still have that. Just missing the clips

This is the 3-4 hub (instead of your 5th) but you can see the clips holding the keys. This is on my 1999 GST but yours most likely will be similar.

Depends on when your 1990 was produced.

Production date before 89.02.04 and you'd need MD742778

after that date and through 90.06.01, you'd need MD742777

I think I’ve found the correct keys on jacks transmissions. Does anyone where the proper shim kit is for the differential?
