1965 MMP's Barracuda Hemi swap! The Ever Changing Build

Just started following your build - absolutely Amazing! I'm doing a '64 Cuda/Gen 3/TKO600 swap. I currently have almost all the QA1 K-member, upper/lower control arms installed, and am curious whose rack & pinion did you use? I know I'll need to switch spindles (whose did you use?)
Not to derail thread but I too used HDK (Hemi Denny) from right here on FABO. Great product great guy. Perfect fit.
