i have personally seen it and it was a fairly simple since the front end is basically a f-series. he did a nice job and it sounds good with the side pipes.
as for putting it in a 78 or older i think the big stuff coms in when you want to add a turbo. i dont think you can put one in without some custom firewall work.
