Yep, home made pulleys and brackets and a home made standard rotation water pump long before the aftermarket ones became available. It was a good fun project and seemed to work pretty good. I had no cooling issues giving it a hard run at Winton.
It's been modified a bit since then. The addition of a Power steering pump changed things a bit. I now have the Alternator running off it's own 4 rib belt using the Aircon pulley grooves on the crank.
The PS pump and water pump run off the 6 rib belt with a separate tensioner which I cant seem to find a decent pic of.
Cheers
