My Cardboard and plywood Stak

[bax]

With my 205 issues lately I have been dreaming about a Stak monster box 3 speed. I have a c6 transmission and the big problem that you run into is the front drive-shaft yoke does not clear the transmission pan unless you use the long shaft c6. With our limited space drive-train length is an issue. Well the Stak input and output center to center are further apart than the 205 by 1 5/8'' I was wondering if this extra width will allow the front drive yoke to clear the c6 pan. I made a cardboard cut out that is to scale. I already had the 205 removed for service so I put the cardboard Stack in place. Problem is the Stak is also wider than the 205 and the 205 just barely fits in the EB. The Stak can be clocked down so I installed my cardboard stak as high up as I could go. It looks to me like everything will work. The front yoke will clear the c6 no problem. I also think it will clear if I was using a short shaft c6. This would save 3'' of drivetrain length. The front shaft is down some and the drive angle is great. I could put 2 more inches of lift without and angle problems up front. The 3'' shorter will move the rear shaft forward and reduce the drive angle , another good thing. the shifter may need some work but it may not be that bad. I took some pictures of my cardboard Stak and I would like to know if the case is clocked too far down in your opinion. It is still under the radius arms. Again I think it would work good. The Stak B box is to narrow and wont clear the trans pan at all.

Roger,
you're spending alot of time under your rig.....

I have a pillow.

It doesn't look like it would be too low to me. But then again, I'd like to see you replace the 205 and then tell us what the next weakest link is.

Seriously though, have you looked into clearancing the C6 pan on that side or is there valve body in the way?

 

[bax]

The 205 is not weak, I just cant get one to stop making noise. my current set up does not need any alterations however like Mad said I am spending too much time under the truck. The c6 pan can be altered because where the valve body is in the pan. The drivers side of the pan has room because the valve body is not in the way. The Stak monster box is pretty big. I just think I like to force things.

What about a Atlas transfer case
It might fit better

There is also a new case that lets to convert a dana 300 to a drivers side front driveshaft

Hey just thought of a crazzy idea, what about borowing a Dana 20 just to confirm the noise it not a rear axle problem

The 20 wont bolt to the c6. The atlas input to output distance is smaller than the 205. I am told it will work if you cut the pan. Tell me more about the 300

You can wiggle another inch or so by loosening all the engine/trans mounts and push the mounting slots to the limit. Maybe even stretch some of the slots a little as well.

I saw somewhere there is a company that builds a new steel case to turn a dana 300 into a drivers drop case. I will see if I can find it.

Though in the meantime take a look at this, as Stak makes a alluminum case that does the same thing

The 300 has the same input to output dimension as the dana 20. It is also less of a case than the 205. It does look like the after market has a lot more options on the build up of a 300 when compared to the ford 205. The atlas is really just an improved copy of a 300.

Bax! With your luck with drivetrains cardboard will never hold up! ;D I was going to mock one up out of plywood with a wooden block with a hole that I could bolt a yoke in.

I ran into the same issue with my C6 and STaK B-Box--not enough room for front driveshaft clearance. So I sold it and bought a regular STaK to play with, following the same lines of thinking as you. I haven't had a chance to mock anything up yet but I've already decided to notch the frame rail for clearance so I could still clock it up high. This is going in a fairly modified rig where that will just be one more thing that got cut. I'll be interested in following your progress, as at the rate I'm going you'll easily beat me to the install.

Dusty, I haven't bought a stak ( yet). I am just trying to figure out what all it is going to take to get it in a bronco. If i put the 205 back in and it still makes noise I just might get one.

Hey Roger
Hold on for a second

I just called Stak to ask them a question about your setup

They are going to be discontinuing the B box very soon. They have a new what they are calling the Chico box, which will be inbetween the two boxes they list on there site now.

They have 5 of these new boxes being tested right now, so maybee if you call them, they might send you a box so you can test it for them. Who knows it is worth a call.

I told them you might call them.

Thanks Don, You the Man.

 

[DonsBolt]

Thanks Don, You the Man.

hehe

your welcome
I am not saying it is the answer to your problems, as your setup might even be a problem for the chico box. But just maybee it might be a option for you.

And it can't hurt to call them, as they might have a solution for you.

I am sure they can give you the dimentions and you can make a new carboard box to see if it will fit, hehe

 

[bax]

Yes Don that is what I have done. I called and got all the new # and will go get the new cardboard Chico box mocked up. It looks like a perfict fit and it will clear the c6 pan by the looks of it. The cardboard will tell. Heck I might even use plywood. Oh by the way UPS just droped off my rebuild kit for the 205. The box was too light, looks like I just got gaskets and seals, no bearings. Thanks! At least when I called they didn't argue with me, like they normally do.

Thanks Don for the information.

OK here is the new Stak case that Don told me about. This case is just a scaled down monster case. The guy ( Tony ) at Stak told me it is about 10 percent smaller. I made a plywood one and mocked it up. It looks really nice and it will clear the c6 pan. It is close but I think it will work. Keep in mind I have a 3'' body lift. With this lift the case hits the frame at the same time it hits the floor. It is tucked up in the frame pretty good I think.

Here's the Dana 300 Flip Kit

I saw that 300 flip. Not interested in going down in strength and the input to output centers are too close for the c6. The 300 is a no go for me.
