I removed the gear housing cause it had a couple of small cracks on it around where it would bolt up to the clutch housing. I figured I would fix it now while it was out before it caused problems later. I took it to a shop and they did a little welding for me. After I got it back though, I wasn't able to get it to close. If I take out the shift forks everything lines up and seals. But with them in, I have just over a 1/2" gap. Does anyone know what might be causing this and how to fix it. BTW, the tranny is a 94 JDM H22A w/ factory LSD. Thanks.
