We all started somewhere, nobody was born with all the vast knowledge of cars and their mechanics. (except for The Stig, TonyD,BRAAP, and the other usualy suspects)
Now, as you would expect, I'm not familiar with how things work in Kuwait. I would expect however that the easiest way of sourcing a LS1/T56 (engine gear box combo) would be from ebay.com or maybe a local engine building garage, or company? Either that or go junkyard hunting with your husband, maybe you will get a lucky break.
