Here's a link to wiper kit that will work for pretty much any street rod:

Specialty Power Windows

Here's a link to a company that sell window channels and rubber products. They also have section dedicated to Internationals:

Restoration Specialties and Supply, Inc.

I doubt you're going to find any fiberglass front fenders for that truck. Your fenders look to be repairable. If so, that would be your best bet, IMO. Even if you have to pay someone to do it.

You might check in restorer mags like Hemmings. You might find some NOS fenders, but they would most likely be pretty expensive. Also, check online for any International clubs. Someone might give you a line on some fenders and other parts.

One word of caution when talking to some restorer type folks. Get a feel for their opinion on street rods before revealing that you have one. I've actually had one guy clam up and refuse to talk to me when he found out my car wasn't original.

You are most likely going to have to make your own patterns for the glass. Any good glass shop can cut safety glass for you. Just make sure they can sand the edges after it's cut. Don't make your patterns until after you have all your channels in place.
