There are many resources on the web for “LS swaps”, and more specifically GBody LS Swaps. The “swap” has been going on since the LS platform engine was introduced in 1995, so there are more resources than you could probably imagine. Here is a list of a few of the resources that have helped me during my “swap” and “restoration”.
