If you were to go with two bushings pressed in, the correct way to do it would be to ream them to size after pressing in. That assures alignment and sizing. I don't know that I would bother with a bearing length that short. If you can't bore them yourself or pay someone to do it to do a one piece full length bushing, I'd sell them as is and put the money towards something better. Just not enough bearing length to support anything but a very mild spring, IMO.
