I am using a 1 1/16 bore master cylinder (manual brakes). It may be too big. I will report back on that after I drive it. It will be on the road this spring. Should be ready sooner, but the weather will make me wait...

Thinking about a few of things...
Camshaft.
Injectors.
Frame connectors.
Anybody have any thoughts on what would work for my setup?
Motor's a '07 vette LS2 with a M1 Procharger, stock internals.
The frame connectors need to be very low profile for ground clearance and I'd rather not cut up my floor.

Got back into the garage today. Finished the front brakes. Pulled the rear diff cover off and pulled one side of the rear brakes apart. More on that tomorrow.
Here's a couple pic's of how it's looking now.

I started working on the back brakes. As usual I was met with a hurdle. I need to replace my wheel studs. I am changing them from 7/16-20x1 and a bit to 1/2-20x1 3/4.(raybestos # 2673B). So as I had to pull my axles anyway for the swap, I am going to do the seals as well. I hope this rear end holds up to the abuse I have in store for it. Worst case I swap in a 12 bolt, as these brakes bolt right onto that axle as well.
I am also lowering the rear 1/2". I got the lowering kit Hotchkis recomended but was not happy with what they supplied. It's hard to tell in the pics, but basically they send you 1/4" shims that you bolt onto the top of the leaf stack in the amount that you want to lower the car. In my case 1/2" or 2 shims. thing is, they dont supply any shims for the side of the stack. So I guess you are supposed to put the shims on top of the leaf, then tighten the U bolts to whatever tourque is recomended and hope that the lower polyeurothane isolator doesn't squish out sideways. I built my own shims, out of 1/4 flat bar, to extend the side mount of the axle tube bracket. It worked perfectly and locates the isolator. Why didn't they think of that?

OK, more troubles... It seems even the simple jobs can take all day, or at least a good portion of them. Went to drill out the axles for the new studs and the drill bit I needed I didn't have. $28 later, for 1 bit, I get the holes done. Then the disks don't sit flush because the center of the hub has a ridge on it. Put the axle in the lathe, spun it and machined it down using a file. (didn't want to risk damaging the bearing surface of the axle with the lathe chuck, so grabbed it further down the axle and it was wobbly) OK got the disk to sit properly. Then pressed in the new studs. (Easiest part of this job) Then found the stud protrudes just slightly past the flange surface, so had to enlarge the holes in the brake disk to make em fit. Done! Yay!
Started the install.Was going well till I tried to centre the caliper over the disk. There is about .050 of axle end play... I need to figure out how to shim that down now. Can't have the disk floating left to right between the pads. It'll make for a soft pedal and unwanted drag on the brakes.

Leave that 10 bolt where it is. Put aftermarket parts in it and you're golden. My buddy runs 9's on slicks with nitrous and transbrake, for 5 or 6 years now. It is plenty strong in stock trim for what you're doing, c-clip eliminators are a good safety upgrade. Very nice build. Good luck and keep the details coming.

Went to my local rear end shop and showed em what I had. Said he hadn't seen one like that in 15 years. Anyway, $1595 plus tax later... well, it was a quote, I'm not quite there yet. I'm thinking that a eaton truetrac may be the way to go, with 30 spline axles. Is this the best setup for road course and auto cross?

Mark- Great build by the way. Amazing attention to detalil. Looks awsome.
I'd like to throw my commnets in about the True-trac to help out if I can. Personally I have one in my Trans Am, also building a road course truck with one in it. My car origionally had the clutch-type LSD. It worked, but even when new it would slip from time to time. Lockers are not a great choice for road racing, can really throw a turn off for you when you try to lay down power and the wheels lock together.
That's where the True-trac does great, it locks together seamlessly but still gives you the benefits of the clutch-type differential. I noticed a huge difference in the way my car put the power down back there. I think you would be thoroghly happy if you made that choice.
As a side note, I've seen all the work you've done there and I don't think a person with your skills would have a hard time doing a gear/diff swap by yourself. There are a lot of online articles out there (that's where I learned) and it's not all that bad really. I've got a few under my belt now just by reading what others have done. Just throwing that out there.
Good luck on the rest of the build!

Mark,
Looking good. What color (shade) blue is your car? I am thinking.... that blue with white stripes and maybe cowl hood for my camaro.
thanks,

Thanks for the compliments! The color is Aston Martin Viper Blue Pearl Metalic. It took a long time to align the eurothane grill and I'm still not happy with it.

Success!! Got the MN12 transmission sorted out and installed. At the end of the day I had to swap the bell housing, hydraulic clutch bearing, shifter, and shifter ball socket thingy. (On the end of the transmission shift shaft). Used the 2 arms and 1 leg on back technique.
At the same time I installed a bulkhead insulated stud for my battery cable. It runs through the inside of the car to the trunk. I had run the cable through a grommet in the firewall but kept having visions of the whole thing going up in smoke. I've found that, with me anyway, if I think of something that could go wrong, it probably will, no matter how remote a chance. Not worth the risk.
