MK1 Capri. Need some advice please

[Mesa]

I've got a MK1 Capri that will in the next few months will be getting a rebuild. Panel and paint are not a problem, it's my trade, and time isn't a factor either.
So far I've managed to source a couple of manuals, each as useless as the other when it come to the black art of wiring. I'm after a good wiring diagram for this model in both GT and standard form. Any suggestions?
Are ther any decent books on Capri's ? In particular, setting up the suspension for amatuer motorsport, and any other tricks former or current racers used to employ back in the 70's.
Finally, what is totally involved in a V8 conversion? The car currently runs a Pinto 4, which isn't too bad, but I'm curious to what's involved to update to a Windsor. I probably won't go the V8 route, but I'd like to know anyway. Thanks guy's and girls.
