02 Frontier Engine Swap

I have a 2002 Frontier 5-speed manual that the engine blew. I bought a used engine from a 2002 Frontier automatic. There was just one little problem with this. The auto engine does not use a bilot bearing for the transmission input shaft. I tried to install the pilot bearing of the manual transmission onto the rear engine but it won't fit. Bearing is too big. So what I have now it that the input shaft of the transmission is fitting loosely onto the rear main.
Does anyone have an input into this? I have been stuck on this for a while now and need this truck back up for hunting season coming up soon. I'm beginning to think it may be ok to just install it as it is, with no bearing. Thanks in advance.

I'm sure all the engines are the same prior to being mated to a transmission.
I don't know how to solve this issue but the bearing is there for support to the shaft. Should you skip using it I imagine the truck will be undrivable.
Possibly you can have a new bearing machined to fit.
Good luck.

I called my dealer and he said the engines should be the same. Are you sure there isn't a bearing in the engine you bought. He said there should have been one.

Good to hear that it's working out for you. After you posted your issue I called my dealer as I needed to be sure what I was thinking was correct and now you confirmed it.
