67 Barracuda rear tire size ?

What is the largest wheel/tire size that would fit with the sping relocation kit and mini tubs in a 67 barracuda conv ? With a stock width a-body 8 3/4 or even cutting down a b-body rear ? I'm used to Darts (no room) and now will be starting this fish ( for my 21 year old son) with a little more open wheel well. It will be street/strip, and will be selling the 5 0 mustang conv to do this !

I guess he finally has seen the light ! :cheers: :cheers: :cheers:
