Hi BBeep. Just discovered your build thread. I guess Oregon boys have extra creativity... I live in West Linn. I'm transplanting some 67 & 68 International Harvester body parts onto the donor chassis/body of a 97 GMC Z71 Extd Cab. And how weird that I am at almost exactly the same stage - getting ready to graft the firewall from the 97GMC onto the cab of the 68 IH. Dealing with the same thoughts you are - how to blend the old cowl air intake - what to do about wiper motor and wiper post mounts.
We probably have similar goals - I want the modern technology but under some older skin. I hope to be cutting my firewalls in about 2 weeks. Still have a few things to strip off the Z71 before the sawzall fires up. Here's a couple of pics.
Sorry for the hijack - can't wait to follow your progress. Great project!
