I have the new trailing links but yet to install them.

I've started a new company and most of my time and resources have been applied to it over the last few months. My shop is full of hydraulics and motion controllers at the moment.

I am loving the axle info on this thread. I'm trying to see if this is a true bolt on plug and play. Let me see if I get it right. So i'm doing a F40 trans on a 3800sc. I hear that the (05-07) Cobalt SS axles are the ones to use. One side bolts to the tranny, and the other bolts to the fiero hub. I need two right side axles and an intermediate shaft for the right side. All from the Cobalt SS. The only thing I need to do is fab up a bracket to bolt to the v6. Did I follow this correctly? If not, please break it down to me like I new nothing about cars and it was my first time. This will save me so much money if this is the route to take for F40 axles. Thanks.

Very nice build by the way!

I think so, but I'm not sure if the f40 and f35 have the same exact differential offset, The 05-07 Cobalt SS axles are the same length on both sides, and will plug into the f40 and the fiero hubs.

I can agree with CC on this one, a customer/friend of mine was looking to install a F40 trans on his cobalt and there was some major issues getting it to fit correctly, in the end he stuck with a stock LSD tranny from a cobalt SS/SC.

Also I don't know how you are going to be mounting the jack shaft setup from a ecotec motor on a 3800 series to use cobalt axles, since the jack shaft bolts to the ecotec and will not have the same locations on a 3800. Not something to completely stop a build, but enough to question the fees-ability of it. I would almost look at a hybrid/custom axle setup with a set of stock cobalt axles and get them shortened or lengthened to remove the use of the jack shaft.

So I start reading this thread and getting all excited 'cuz someone already did my build - and depressed, 'cuz there's no WAY I'm gonna do all that fabrication.

And then I see an old friend, Coppertop, doing the same thing, starting from the same place. And designing a custom cradle, no less.

'sup, Coppertop?! Sally's drivetrain is looking for a mid-mounted new home.

How's all this coming? And is that new cradle order-able yet?

BigBrother.........sorry I don't recognize your handle, unfortunately I have a bad memory for names, but I remember peoples cars.....lol

As for the cradle, my project is running about a year behind my initial schedule, although the project has taken a life of its own and isn't what my original plans were. I'm hoping this winter to have all the major mechanical done enough that I can disassemble the car and complete the welding and maybe start the finishing and assembly next year, until I test the cradle in my running car I don't feel like being responsible for a untested product.

I have the same handle on RLF and CSS. Pacific Blue 2005 competition package. Big wreck in March totaled her. I'm sure I know you from the other boards better than you know me, given you're right up there with John (Qwik) in the "done a ton for the community" category, lol.

I am in the process of learning AutoCAD and Inventor; workers comp sent me to school when the 1st wreck (on the clock) left me unable to work for my old employer anymore. Unfortunately they're only paying for the "101" type courses for each, so I have a lot to learn still - BUT - they DID get me a top of the line HP mobile workstation and the ENTIRE AutoDesk suite complete with a 3 year professional subscription.

So if I can help, let me know..!

Thats why I don't recognize the handle, I personally banned RLF years ago due to their views on vendors and their pricing to be a vendor.........and CSS used to have a lot of good info, now I find it a bit of a flame battle forum. I wouldn't put me up with John, he's done a butt load more than I have in the delta chassis world.......but it does help being 45 mins from his shop

Sorry to hear about your crash, but good luck with the schooling, I find it nice to sit down and design new stuff, don't get too overwhelmed with it, I am completely self taught and still learn new things with it all the time.
