Does anyone have what the measurement are on the engine perch move. I have just started working on the same swap and have cut off the old mount very carefully. The big difference is I am working with just the frame at the moment and I don't have a transmission cross brace/skid plate to base my engine location off of. I will start a post on my build here after I get done doing some work on mine today.

Awesome! Any of you guys with a donor still have two ECU wires you can pull out and send me (I'll pay for em) No junkyards around here for hours around. Injector wires and the transfer case input gear are all I need now. I have EVERYTHING else waiting in the garage.
