From what I recall it was near 70 inches. That is wider than the fenders and rear 1/4 panels which is why I had to widebody and flare my sheetmetal on all 4 corners.

Good luck.

Thanks for posting. So my plan was to replace my rear frame rails, adding a front crossmember to be able to move the legs inboard and to also mount subframe connectors. Im eliminating the dipdown in the trunk to do so, basically keeping stock sheet metal and clearancing where i need to. Do you know the diameter of the torque tubes, was yours shortend/lengthend, and if it would fit under the stock tunnel? Also wondering how far the transmission comes into the cabin

Do you think cutting (narrowing) the rear crossmember is a good idea? one of my friends is a welding wizard, just seems to me that there would be a lotta stress on the welds. Did you ever conside having a narrowed tubular crossmember made and copying all the suspension and diff mounting locations, to avoid flaring the fenders? definitly easier said then done. For the UCA's, did you copy the C5 specs for the mounting locations?

sorry for the rant, but im sure you have the most 1st hand experience with the C5 IRS swap.

here is a video of the finished product of the 68 with C-4 rear. Turned out pretty good!

Kyle,
Very cool product. I bet people would like to know the price...:thumbsup:

Kyle,

Can you list some benefits of the IRS vs the torque arm?

Anyone heard of Ame multilink?

David Pozzi just installed one in Mary's car.... I believe he's also writing a magazine "how to" article -- her car is a second gen...

Thanks for the bump on this one... I liked re-reading the trash talk between Todd and Gaetano. :catfight:

:lol:

I don't see one post in here form Tracky :confused59:

Oh right. I can see things you can't. Gaetano wisely deleted his posts. I'll leave it at that. :lol:
