US Car Tool leaf spring relocation, misc Help

I recently installed the US Car Tool inboard leaf spring kit in my 71 Cuda, was wondering if anybody has used the same kit and if so what was their final rim and tire combo?

I have a few variables, as i have a dana from a 67 b-body, and with the kit i have gained quite afew inches.

Appreciate any comments.

Ps with the kit i had to reweld my perches, whats the factory pinion angle?
