Default 231 synchronizer hub...anyone know?

Alright, many of you know that I am in the process of rebuilding my t-case. I split the case yesterday and found the problem...

When I opened up the case there were large amounts of shavings in the bottom as well as a spring/snap ring that I have since identified as having come from the synchronizer assembly.

I have solved all the other problems (as far as I see) except the reassembly of this synchro. Does anyone know where this spring goes? I know it somehow is meant to hold some pad looking things in place, but there are two of these springs and three pads and I just don't know.

I am at class right now, so pictures aren't possible, but I will take some tonight when I get home and hopefully let you all see what I am talking about.

here is a pic of a std synchro



The spring fits inside of #3 it holds the blockers #8 in place.
The tab (if it has one) on the spring fits in the underside of #8

rabbler, thanks so much. The question I have now though is that I have two springs and three blockers (#8). Do I stack the springs on top of each other and then leave the third blocker to fend for itself or what?

No 1 spring goes on each side of the synchro hub (#8)
You will have to press that hub (#8) off the shaft again.
You should be able to position that spring so it touches all 3 blockers.
Are you replacing the syncro (#7 shiny brass thing)too?

No. I'm not replacing anything. The parts are all still good, but the pads on the shift forks had all busted apart. I believe that gave everything enough play that it allowed the hub to seperate like it did. After looking at it closer, I ended up putting those springs on either side just because that looked about right. I haven't put the snap ring back on yet though, just in case I was wrong. I guess I would be okay to do so now, eh?

I put the tabs from each of the springs in different blockers though, I'm assuming that's how it's suppose to go?

Thanks rabbler. I'll piece the rest of it back together after work. I've only got one more seal to replace and then reassemble the darn thing.
