As part of my leaving the GT40 world (I've sold my car and it ships to Europe in a couple of days), I've scanned and uploaded several documents to my company web site. The clutch drawing is in a pdf file at the following website url http://www.sierra-networks.com/GT40_001-Clutch.pdf I'll leave them up for a while. I tried uploading them here, but had issues. If someone else wants to upload them, you have my permission. I'm also posting the KVA instructions that I received, the JW Automotive GT40 Parts Manual, GTD build manual, a JW Automotive Electrical Wiring Diagram, and possibly other information.
Hope everyone finds something useful.
