420A Transmission end bearings

[Eclipse420aTuner]

Rebuilding the 420a transmission and ran into a snag..

Before full examining the end bearings, I tossed the old ones since I have some nice, new ones in my trans rebuild kit---rookie mistake! One does not seem to fit properly and they appear to be different sizes. Before I go trying to jam the one in that seems a little too large with the press, I wondered if anyone knows the answer to this question--are they supposed to be identical? Perhaps I got the wrong one in the kit or if it is correct, which goes on the input and output shafts?

The larger one has writing "TM2/32 NSK 106" and "30TEM31ANX." The slightly smaller one says "30TM 14NX1."

I do have the transmission manual I found floating in the internet and it just doesn't get specific enough to answer this question and a Youtube video from CarModsGarage shows the end bearing on both shafts to look about the same size to me.

Any help is greatly appreciated! Attached are the end bearings.

They are both the same size. I swapped the positions of mine to account for even wear.

Same part numbers, same size.

Well the bearings are supposed to be 63mm OD but I can tell you that the aftermarket ones typically screw up with the end bearings. The OEM ones are NSK 30TM14NX1. The aftermarket kits have some that specify the sizing, but the BK414WS kit i just received was sent with 66mm OD bearings and was missing the INA F390112 input shaft sleeve bearing, which is wrong of course, as the 66mm bearings are supposed to be in the BK414AWS kits. Frustrating to say the least. Still waiting on them to resolve the problem with my order.

The rebuild kit from Transmission Parts Distributors fits and works great. They also sell the parts individually.

Stay away from All State Gear. They still have not resolved my order from a month ago with over a dozen emails sent. Their kit also came with fiber lined 3/4/5/R synchros.

I've used Transmission Parts Distributors before for other applications, did your kit come with full brass synchros for 3/4/5/R, along with the correct end shaft bearings and input shaft sleeve bearing?

@twicks69 I didn't mess with the input shaft at all. But yes the synchros they sell are full brass with a steel ring. And the end bearings are identical to the stock ones (besides the number on the plastic cover).
