You should have no problem building one good box out of those two if they are the same type. Keep in mind that there are different JB3 transmissions available, check the type codes carefully.
I would suggest that you get for example the Haynes manual, it has very good instructions on disassembling/assembling the gearbox.
First you need to remove the 5th gear gears and then you are able to open the box. If it doesn't open easily, try engaging different gears. If I remember correctly, you need to have it on certain gear for it to open easily. Can't remember which one it was.
I have the manual so I can give you exact instructions if you want but I strongly suggest on getting the manual yourself. The gearbox is full of small pieces that can come of when you open it. At least that has happened to me...

Beware which Haynes manual you get, the version I have (it's dark green) has no information at all on the gearbox.

Hi, I got it scanned. It's a PDF so I can't really post it here. I can send it to you by email, if that's okay?
