My new synchro plates will not easily fit into the hub, whereas the old ones fit freely. I’m using the original hub. Any suggestions?

Willys Jeep Parts Tech:
Give us a call and we can help you out on that. Thanks!

is there anyway possible to put these in without removing the trans from the jeep ? stupid question maybe but 2nd just grinds and wont sync so I noticed paws were gone . just put jeep back together and don't want to take back apart if I can help it

Willys Tech:
You will pretty much need to remove the transmission. Its possible im sure but it would be difficult.

Does this 2.79 price come with (3) synchronize rs or do I order 3 at 2.79 each?

Willys Tech:
These are sold each.

Can you make 1st gear sync?

Willys Tech:
No T90 transmissions were never syncronized there. You just have to come to a complete stop.

Does first gear in the t 90 syncronized.? If so what is cost?

Willys Tech:
The T-90 was never syncronized in 1st gear. Only 2nd and 3rd are synchronized. You have to be at a full stop to downshift from 2nd to 1st.
