That's why I got a spool. I had a mini spool laying around. When I tired to fit the mini spool. There was no way I could fit that thing in there. So I stuck it back on the self and got a spool.

I've read that the mini-spools are made for the open (non trac lok) rear ends. I wonder if the axles are different length in an open rear?

It's has nothing to do with the alxes as long as they have the same spline alxes. It's because the mini spool wont fit in the trac lock housing. A open rear has a bigger housing so the mini spool fits right in there.

Are you sure about the bigger housing? The housings look the same to me -- I would think it's more room inside because of the open setup vs. the Trac-Lok.

That's what I mean it's bigger inside so the mini spool would fit inside of it. Trac-lok is small. I don't mean the housing itself. I mean inside. It clearly says in the instruction that a mini spool will only work with open rear end housings. Will not work with Trac-lok.

I just don't like mini spools there is still something to break with them. My dad use to have a mini spool in with 79 Capri. We broke three pins in the mini spool. I guess 6000rpm and side step the clutch it just can't hold up. That why I put a spool in my mustang. Well that and I just couldn't get the mini spool to fit inside the trac-loc housing. I have a spool in my racecar so I thought what the hell. I'll put one in my mustang.

I got my mini spool from jegs to it's a Richmond. Mine also came in two pieces with the block thing. Then the cross pin goes in it.

yeah it hast to be in pieces so it can be compatible with the cclips. those 2 blocks rattle slightly and with rpm they are noisy. but id enver go back to a trac loc. i love the way it feels with the axles locked together.

Later down the road get a spool. It wont make any nosie. There's nothing to them and you can't break anything with them. Like I said before my dad broke three cross pins in his mini spool. He has some power. He has a 351 .030 over. 356ci. It goes 11.50's@117. When he broke the cross pin it slammed down and bottom out. Wheels up and then slammed down. It sucked. But oh well it's only a street car. He doesn't race it anymore.

theres a screw in the trac loc housing that goes through the crosspin and prevents it from coming out. how did it come out? he must have alot of power.

I wish I had pictures. I didn't come out it just broke.

lol wow! better get a hardened one next time. i believe a hardened crosspin is required when you go with 4.30s for some reason.

We had 4.56 gears. But now it has a spool and 3.89 gears for the street.

i am thinking of getting a small stiff spring at autozone similar to a valve spring and install it between those 2 blocks. the cross pin will then go through the trac loc and this spring to keep it in place and will put force on the blocks and prevent the clunking noise they create.

I wonder if some of the clunking isnt coming from the posi pack that you used for spacing.

Oh btw I just finished installing mine. It took me about 5 tries to get the right thickness of shims and clutch parts to make it fit snug.

I have no idea how you couldnt fit the 3 piece mini spool in the carrier, there was nothing but room.

The first line of the directions state "For open differantial carriers only, not for posi unts".
