Boss Frog Differential Subframe and Axles
They finally released some details and pricing on these items. I think I will be placing an order in a month or two. Will definitely be a step in the right direction for me and when I do eventually do an LS swap I won't need to worry about messing with the rear end at all. Any thoughts or opinions?
Here's a link to their site if you aren't familiar with the kit:

Interesting. $350 for the "kit", but then axles are $1750! I might would buy the stuff to bolt in a 8.8 and then make my own CV joints.
And funny thing is the t-birds had a 7.5" IRS diff, not the 8.8 IRS IIRC. 8.8's were for Cobra Mustangs and Lincoln Mach VIII's. I think, anyways.

The biggest he said was the 2.25" that they are currently running. I could fit duals, but I don't really want to unless I don't have any other options.
The more I look at the costs involved with any of the rear ends offered, the more I really want to just forget buying a kit from someone and just have it all custom made.

And that is why the v8roadsters kit uses the CTS diff. It is new, available for around $5-600 on car-part.com and much smaller than the ford diffs. I believe they are using up to 3" exhaust on their car. Still extremely expensive, but the boss frog kit doesn't come with the diff either. Both kits are exactly the same price when you get the complete conversion.

Something is wrong when its cheaper to go out and buy all the tools + axles you need then to buy BOSS axles!!! I found 3 places that all could custom make CV axles to just about any conversion you wanted for 225$-250$ per side
BOSS AXLES - 1750$
Custom made axles - 500$
MIG welder 500$
Torch 400$
total 1400$

I doubt many will be running a 500hp+ car with slicks. Wheel hop seems to be the demise of the CTS diff in the highly tuned CTS-Vs out there. I'll be traction limited most of the time so I don't see a problem in killing the rear end.
FWIW, FM is doing a few LS3 swaps so they're starting with cars closer to that power point.
