Good progress so far!
Weird, It looks like you got only the sikky billet pedestals. My sikky kit came complete with mount plates that sandwich in between the frame rails and subframe, oil pan, and oil lines. Also, the sikky kit places the engine back further than any other kit I've seen. You have to trim the firewall lip and bash the firewall to get it to fit. My GTO T56 shifter fit perfectly centered in the shifter hole with no adapters. It does sit slightly higher, but still clears the stock hood with only minor trimming to the webbing/brace, and leaves the steering rack in factory location, so no bump steer kit is required! Either way, good work! You'll love the car!
